Abstract

An original way to obtain fibers with special chromatic dispersion and single-mode behavior is to consider microstructured optical fibers (MOFs). These fibers present unique optical properties thanks to the high degree of freedom in the design of their geometrical structure. In this study, the first all-solid all-chalcogenide MOFs exhibiting photonic bandgap transmission have been achieved and optically characterized. The fibers are made of an As38Se62 matrix, with inclusions of Te20As30Se50 glass that shows a higher refractive index (n = 2.9). In those fibers, several transmission bands have been observed in mid infrared depending on the geometry. In addition, for the first time, propagation by photonic bandgap effect in an all-chalcogenide MOF has been observed at 3.39 µm, 9.3 µm, and 10.6 µm. The numerical simulations based on the optogeometric properties of the fibers agree well with the experimental characterizations.

Abstract

The mid-infrared spectral region is of great technical and scientific importance in a variety of research fields and applications. Among these studies, mid-infrared supercontinuum generation has attracted strong interest in the last decade, because of unique properties such as broad wavelength coverage and high coherence, among others. In this paper, the intrinsic optical properties of different types of glasses and fibers are presented. It turns out that microstructured chalcogenide fibers are ideal choices for the generation of mid-infrared supercontinua. The fabrication procedures of chalcogenide microstructured fibers are introduced, including purification methods of the glass, rod synthesis processes, and preform realization techniques. In addition, supercontinua generated in chalcogenide microstructured fibers employing diverse pump sources and configurations are enumerated. Finally, the potential of supercontinua for applications in mid-infrared imaging and spectroscopy is shown.

Abstract

International audience; The heterojunction between two materials brought into contact, for example, in the form of vertical van der Waals heterostructures, exhibits interesting features offering functionalities to devices stimulated by light. We report in this article an investigation of the optical and electronic properties of the heterojunction formed between Sb2Se3, a material with a promising role in photovoltaics characterized by one-dimensional (1D) topology (ribbons), and an emerging two-dimensional (2D) material, PtSe2, exhibiting unique optical properties for photoelectronics and photonics. The controlled growth of PtSe2 on Sb2Se3 underlayer takes place using a transfer-free process by low-temperature selenization of 1-2 nm Pt films thermally evaporated on Sb2Se3 ultrathin substrates. X-ray photoelectron spectroscopy (XPS) data analyzed in the context of the Kraut method provided an estimate for the band offsets at the interface. The valence band offset and the conduction band offset of the PtSe2/Sb2Se3 heterojunction were found to be -0.25 and 1.0 eV, respectively, indicating a type-II heterojunction. The ultrabroad optical absorption of the heterojunction and the protection offered by PtSe2 to Sb2Se3, against oxidation of the latter, render this particular heterojunction a robust candidate for applications in photovoltaics. Finally, the current study of a heterojunction between materials of different dimensionalities may pave the way for a rational design in the field of trans-dimensional heterostructures.

Abstract

International audience; The production of chalcogenide microstructured optical fibers with low optical losses, due to the broad transparency window of these glasses in the mid-IR, can allow for new breakthroughs in various research fields, e.g. new mid-IR laser sources and mid-IR spectroscopy. In this framework, high purity chalcogenide glasses are needed in order to minimize absorption losses. In this study, Ge10As22Se68 samples were prepared using a double distillation method, using different combinations of chlorides and metals as getters for the physico-chemical elimination of carbon, oxygen and hydrogen impurities. Comparing the attenuation spectra of the different samples, the choice of the getters seems to be indeed a significant factor in the quality of the glass. A holey fiber has been realized by casting method using the best sample, showing that the method is suitable for this composition and that the attenuation before and after the casting are comparable.

Abstract

International audience; For several years, chalcogenide glasses have been studied as good candidates for numerous applications in the midinfrared region. Indeed, these glasses are transparent from 1 to 20 μm (depending on the composition), a mid- IR windows well-suited for sensing molecules whose optical signatures are located in the 2-16 μm range. In addition, thanks to appropriate thermal properties, chalcogenide glasses can be drawn into fibers, including microstructured optical fibers. In this work, a new method based on 3D-printing process is investigated to produce hollow chalcogenide glass preforms, which are then drawn into hollow-core fibers. The transmission of the "printed"hollow-core fiber has been measured and compared to the initial glass. A significant, but still manageable, increase by a factor of 2.5 is observed. This works opens a promising way for the fabrication of chalcogenide MOFs, more particularly for the elaboration of hollow core fibers. © 2021 SPIE.

Abstract

Despite the renewed interest in rare earth-doped chalcogenide glasses lying mainly in mid-infrared applications, a few comprehensive studies so far have presented the photoluminescence of amorphous chalcogenide films from visible to mid-infrared. This work reports the fabrication of luminescent quaternary sulfide thin films using radio-frequency sputtering and pulsed laser deposition, and the characterization of their chemical composition, morphology, structure, refractive index and Er3+ photoluminescence. The study of Er3+ 4I13/2 level lifetimes enables developing suitable deposition parameters; the dependency of composition, structural and spectroscopic properties on deposition parameters provides a way to tailor the RE-doped thin film properties. The surface roughness is very low for both deposition methods, ensuring reasonable propagation optical losses. The effects of annealing on the sulfide films spectroscopy and lifetimes were assessed. PLD appears consistent composition-wise, and largely independent of the deposition conditions, but radiofrequency magnetron sputtering seems to be more versatile, as one may tailor the film properties through deposition parameters manipulation. The luminescence via rare earth-doped chalcogenide waveguiding micro-structures might find easy-to-use applications concerning telecommunications or on-chip optical sensors for which luminescent sources or amplifiers operating at different wavelengths are required.

Abstract

Compared to oxide based glasses, vitreous materials composed of chalcogen elements (S, Se, Te) show large transparency windows in the infrared. Indeed, chalcogenide fibers can be transparent from the visible up to 12-15 μm, depending on their compositions. The IR signatures of most molecules, including biomolecules, are located in this spectral domain, which allows in situ, non-invasive and real-time detection of gaz or organics molecules. Indeed, chalcogenide glasses can present a high non-linear coefficient (n2), 100 to 1000 times larger than for silica glass, depending on the composition. An original way to obtain fibers is to design microstructured optical fibers (MOFs). These fibers present unique optical properties thanks to the high degree of freedom in the design of their geometrical structure. Various chalcogenide MOFs operating in the mid-IR range have been elaborated in order to associate the high nonlinear properties of these glasses and the original MOF properties. Different glass compositions and different designs have been achieved depending on the intended application. Indeed, chalcogenide MOFs might lead to new devices with unique optical properties in the Mid-IR domain like multimode or endlessly single mode transmission of light, small or large mode area fibers, non-linear properties for wavelength conversion or generation of supercontinuum sources. In this work, a supercontinuum from 2 to 10 μm, with an average power of 15mW, has been obtained in a chalcogenide MOF by pumping with a supercontinuum generated in a fluoride fiber.

Abstract

International audience; In the frame of the major issues related to global warming and pollution, the microsensor based on mid-infrared (MIR) spectroscopy is a useful tool to allow continuous measurement of different bio-chemicals species that disturb our environment. In the aim of developing a MIR source potentially integrated in a microsensor, we fabricated rare earth doped chalcogenide thin films by different phase vapor deposition (PVD) technics. The RF magnetron sputtering, pulsed laser deposition (PLD) and electron beam evaporation were investigated.The selected glass system is Ge-Ga-(Sb)-S with Er3+ ions doping. Er3+ ions show emissions in NIR and MIR at 1.55 µm (4I13/2→4I15/2)and at 2.8 µm (4I11/2→4I13/2) under excitation at 808 nm. Deposition parameters were optimized for the three PVD techniques based on a comparison to define the higher fluorescence efficiency. Sulphide thin films were characterized by means of transmission, AFM, XPS, SEM, EDS, ellipsometry and Raman spectroscopy to better control the deposition behavior.

Abstract

International audience; The mid-infrared molecular fingerprint region has gained great interest in the last decade thanks to development of on-chip semiconductor lasers and mid-IR optical fibers. For integrated-optic devices and optical sensors based on interferometric techniques, versatile and easy handling devices can be required. In this context, low-loss single-mode chalcogenide microstructured optical fibers (MOF) which presents an antireflection coating have been elaborated in order to be connected to a Distributed Feedback Quantum Quantum Cascade Laser (DFB-QCL). In addition, another original design of a chalcogenide MOF has been also realized in order to obtained high birefringence properties that can permit to maintain the polarization of the QCL at the output of the fiber. Finally, the fiber properties have been evaluated using a DFB-QCL emitting at 7.4 µm and the polarization maintaining of the chalcogenide fiber has been demonstrated[2]. The combination between a DFB-QCL with such non-conventional fibers has led to the development of single-mode fibered Mid IR lasers.

Abstract

We report the fabrication of a microstructured optical fiber drawn from a soft glass 3D printed preform. For this proof of concept, a chalcogenide glass that is well known for its capability to be shaped at low temperature and its mid-infrared transmission was selected: Te20As30Se50. The obtained negative curvature hollow core fiber shows several transmission bands in the 2–12 µm range that are reproduced numerically using finite element-based simulations and coupled mode theory.

Abstract

International audience; The mid-infrared spectral region is of great technical and scientific importance in a variety of research fields and applications. Among these studies, mid-infrared supercontinuum generation has attracted strong interest in the last decade, because of unique properties such as broad wavelength coverage and high coherence, among others. In this paper, the intrinsic optical properties of different types of glasses and fibers are presented. It turns out that microstructured chalcogenide fibers are ideal choices for the generation of mid-infrared supercontinua. The fabrication procedures of chalcogenide microstructured fibers are introduced, including purification methods of the glass, rod synthesis processes, and preform realization techniques. In addition, supercontinua generated in chalcogenide microstructured fibers employing diverse pump sources and configurations are enumerated. Finally, the potential of supercontinua for applications in mid-infrared imaging and spectroscopy is shown.

Abstract

In this work, we present for the first time the concept of chalcogenide glass-ceramic for photovoltaic applications with the GeSe2–Sb2Se3–CuI system. It has been demonstrated that thin films, deposited with the sputtering technique, are amorphous and can be crystallized with appropriate heat treatment. The thin film glass-ceramic behaves as a p-type semiconductor, even if it contains p-type Cu2GeSe3and n-type Sb2Se3. The conductivity of Sb2Se3has been greatly improved by appropriate iodine doping. The first photovoltaic solar cells based on the association of iodine-doped Sb2Se3and the glass-ceramic thin films give a short-circuit current density JSCof 10 mA/cm2and an open-circuit voltage VOCof 255 mV, with a power conversion efficiency of about 0.9%.

Abstract

The detection of molecules dissolved in liquid medium can be envisaged by means of an optical integrated sensor operating in middle infrared range. The intended sensor is composed of a cladding and a guiding selenide sputtered layers transparent in middle infrared. Hence, Ge-Sb-Se thin films were selected in view of tailored refractive index contrast, successfully deposited by radio frequency magnetron sputtering and characterized. To maximize the evanescent field at a wavelength of 7.7 µm, a suitable selenide waveguide allowing measuring the optical transmitted power was designed by performing computer simulations based on the effective index method enabling single-mode propagation for a waveguide width between 8 and 12 µm. Selenide sputtered films were micro-patterned using reactive ion etching with inductively coupled plasma process. Finally, optical waveguide surface was functionalized by the deposition of a hydrophobic polymer, which will permit detection of organic molecules in water.

Abstract

Chalcogenide glasses are known for their large transparency in the mid-infrared (Mid-IR) and their high nonlinear optical properties. Indeed, chalcogenide glasses can present a high non-linear coefficient (n2), 100 to 1000 times larger than for silica glass, depending on the composition. An original way to obtain fibers is to design microstructured optical fibers (MOFs). These fibers present unique optical properties thanks to the high degree of freedom in the design of their geometrical structure. Various chalcogenide MOFs operating in the mid-IR range have been elaborated in order to associate the high nonlinear properties of these glasses and the original MOF properties. Different glass compositions and different designs have been achieved depending on the intended application. Indeed, chalcogenide MOFs might lead to new devices with unique optical properties in the Mid-IR domain like multimode or endlessly single mode transmission of light, small or large mode area fibers, non-linear properties for wavelength conversion or generation of supercontinuum sources. In the 1-12 µm window, single mode fibers, polarization maintaining fibers and exposed core fibers have been realized for Gaussian beams propagation and sensors applications. In this context, different applications such as Brillouin laser, all optical demultiplexing, mid-IR supercontinuum generation, quantum cascade laser pigtailing and mid-IR spectroscopy will be exposed.

Abstract

The paper describes the design of a medium infrared fiber laser based on a dysprosium-doped chalcogenide glass $\text{Dy}^{3+}: \text{Ga}_{5}\text{Ge}_{20}\text{Sb}_{10}\text{S}_{65}$ . To obtain a high efficiency, the fiber laser is followed by an optical amplifier. The optimized optical source exploits a master oscillator power amplifier (MOPA) configuration. The MOPA pump and signal wavelengths are 1709 and 4384 nm, respectively. Spectroscopic parameters measured on preliminary samples of chalcogenide glasses are taken into account to fulfill realistic simulations. The MOPA emission is maximized by applying a particle swarm optimization approach. For the dysprosium concentration ${\text{6}}\, \times\, {\text{10}}^{25}$ ions/ $\text{m}^{3}$ and the input pump power of 3 W, an output power of 637 mW can be obtained for optical fiber losses close to 1 dB $\text{m}^{-1}$ . The optimized MOPA configuration allows a laser efficiency larger than 21%. By considering the high beam quality provided by photonic crystal fibers, it is a good candidate for medium infrared light generation whose main applications include, but are not limited to, molecular spectroscopy and environmental monitoring.

Abstract

International audience; An original way to obtain fibers with special chromatic dispersion and single-​mode behavior is to consider microstructured optical fibers (MOFs)​. These fibers present unique optical properties thanks to the high degree of freedom in the design of their geometrical structure. In this study, the first all-​solid all-​chalcogenide MOFs exhibiting photonic bandgap transmission have been achieved and optically characterized. The fibers are made of an As38Se62 matrix, with inclusions of Te20As30Se50 glass that shows a higher refractive index (n = 2.9)​. In those fibers, several transmission bands have been obsd. in mid IR depending on the geometry. In addn., for the first time, propagation by photonic bandgap effect in an all-​chalcogenide MOF has been obsd. at 3.39 μm, 9.3 μm, and 10.6 μm. The numerical simulations based on the optogeometric properties of the fibers agree well with the exptl. characterizations.

Abstract

Groundnut shell was crushed in to particle size and given two surface treatments with alkali and 3chloro-2-hydroxylpropyltrimethylammoniumchloride respectively. The raw, alkali-treated and bonding agent treated groundnut shell cellulose fibers were used as natural rubber composites. The samples were used to produce fiber-reinforced natural rubber composite at varying filler loadings. Properties such as tensile, hardness and impact of the composites were investigated. The tensile strength of the composites varied such that both the alkali-treated and cationized fillers recorded higher values than untreated fillers. The impact hardness properties were also found to be better in the modified fillers than the untreated ones. This work has shown some general improvements arising from cauticization and cationization of cellulosic filler as reinforcing material for natural rubber.

Abstract

This paper reports the fabrication of luminescent optical rib/ridge waveguides made of erbium doped Ga-Ge-Sb-S films deposited by RF magnetron sputtering. Several fluorescence emissions of Er 3+ ions from the visible to the middle infrared spectral domain were clearly observed within the films. The study of the 4 I 13/2 level lifetime enabled development of a suitable annealing treatment of the films to reach the value of the bulk counterpart while the variation in surface roughness was limited, thus ensuring reasonable optical losses (0.7–0.9 dB/cm). Amplification experiments were carried out at 1.54 μm leading to complete characterization of the erbium-doped micro-waveguide with ∼3.4 dB/cm on/off gain. A demonstration of mid-IR photoluminescence from Er 3+ -doped chalcogenide micro-waveguide was recorded at ∼2.76 μm. The multi-luminescence from the visible to mid-IR generated using erbium doped chalcogenide waveguiding micro-structures might find easy-to-use applications concerning telecommunication technologies or on-chip optical sensors for which luminescent sources or amplifiers operating at different wavelengths are required.

Abstract

Compared to oxide based glasses, vitreous materials composed of chalcogen elements (S, Se, Te) show large transparency windows in the infrared. Indeed, chalcogenide glasses can be transparent from the visible up to 12 – 18 µm, depending on their compositions. In addition, chalcogenide glasses contain large polarisable atoms and external lone electron pairs which induce exceptional non-linear properties. Consequently, the non-linear properties can be 100 or 1000 times as high as the non-linearity of silica. An original way to obtain single-mode fibers is to design microstructured optical fibers (MOFs). These fibers present unique optical properties thanks to the high degree of freedom in the design of their geometrical structure. Our group has prepared various chalcogenide MOFs operating in the IR range in order to associate the high non-linear properties of these glasses and the original MOF properties. Indeed, chalcogenide MOFs might lead to new devices with unique optical properties in the mid-infrared domain like multimode or endlessly single-mode transmission of light, small or large mode area fibers, highly birefringent fibers and non-linear properties for wavelength conversion or generation of supercontinuum sources.

Abstract

Fiber lasers are a fast growing class of lasers due to their reliability, efficiency and flexibility. This has made fiber lasers a versatile tool for manufacturing, sensing and healthcare, not forgetting the contribution of Erbium-doped amplifiers to optical communications. Yet available wavelengths by direct emission are quite restricted to the visible and near infrared wavelength interval (500 nm to 2 micron), with very few offering high power and efficient operation, namely 1 micron, 1.5 micron and 2 micron wavelengths. In this paper we comment on the state of the art and future challenges in the field of fiber lasers to address new wavelength and new applications. In particular to extended the emission interval above 3 micron. This work collects the experience of the COST MP1401 Network on fiber lasers and their application and will present some of the areas were efforts have been focused. More exhaustive material will be presented at the conference.

Abstract

The deposition of Ge25Sb10S65 and Ge25Sb10Se65 amorphous chalcogenide thin films was performed by radio-frequency magnetron sputtering and pulsed laser deposition technique. The deposited layers were characterized by studying their morphology, topography, chemical composition, structure, and optical functions permitting a direct comparison of two deposition methods for obtaining attractive amorphous chalcogenide films. Reactive ion etching was then used to pattern rib/ridge waveguides in sulfide and selenide films with low surface roughness, vertical sidewalls, and reasonable etching rate. Optical losses of fabricated waveguides were measured at 1550 nm with values better than 1 dB/cm obtained for sulfide/selenide films deposited by both techniques.

Abstract

International audience; The present study relates to a new method for the synthesis of As2Se3 glass in a controlled atmosphere. The advantage of this technique is that it does not require sealing of the silica reaction container and therefore makes it likely to substitute the current industrial batch by batch synthesis which actually needs very expensive single-use sealed silica vessels. An experimental device has been developed for these purposes. It is equipped with a stirring mechanism to homogenize the molten bath. In order to avoid contamination by oxygen and moisture, the synthesis is carried out under argon flow (pressure of 1 bar). Material losses during synthesis can be reduced to less than 2% when temperature is progressively increased up to 430 °C. Bulk glass ingots are finally obtained according to a two-step annealing process. Their chemical composition is analyzed by EDS and shows a variation range of less than 0.2%. The excellent reproducibility of the given method is also confirmed by the refractive indexes, that do not differ for more than 1 * 10−3 from one another. Adverse absorption bands due to oxygen do not occur in the 8-12 μm spectral region when 1000 ppm of Mg is added. As no distilling operation has been carried out until now, the magnesium oxide partially keeps staying in the glass and leads to scattering losses at short wavelengths.

Abstract

Unclad optical fibers based on Ge–Sb–S glass systems were prepared by preform drawing. It was shown that optical losses in fibers depend on the content of limiting impurities in glass. The correlation between the level of optical losses in fibers and the content of gas-forming dissolved impurities and heterophase inclusions in glasses was established. The minimum optical losses were equal to 300 dB/km at 5.35 μm wavelength in fiber from Ge 25 Sb 10.5 S 64.5 glass prepared using chemical-distillation melt purification.

Abstract

International audience; In the present work, thermal properties of GeSe2-As2Se3-CdSe glasses were investigated via DSC measurements. The dependences of glass transition temperature and thermal stability on glass composition were discussed. XRD measurement was also performed to validate the effect of cadmium on the thermal properties of glasses. The calculated Avrami exponent was used to demonstrate the three-dimensional growth of crystals in the glass matrices. The crystallization kinetics for the glasses was studied by using the modified Kissinger and Ozawa equations.

Abstract

International audience; Optical properties and photoluminescence of PbS quantum dots (QDs) embedded in glasses were investigated. Formation and radius of PbS QDs were carefully controlled though heat-treatment and modification of host glass composition. Heat-treatment conditions for precipitation of 3-10 nm radius QDs for the tunable photoluminescence in the 1-2 μm wavelength range were identified. Glasses doped with PbS QDs provide potential as robust materials for broadband fiber-optic amplifiers.

Abstract

Compared to oxide based glasses, vitreous materials composed of chalcogen elements (S, Se, Te) show large transparency windows in the infrared. Indeed, chalcogenide glasses can be transparent from the visible up to 12 – 15 µm, depending on their compositions. This is due to the lower phonon energies of chalcogenides, which are also responsible for enhanced luminescence of rare-earth ions embedded in such matrices. Thus, sulphide glasses, for instance, allow light emission at wavelengths not accessible with silica. In addition, chalcogenide glasses contain large polarisable atoms and external lone electron pairs which induce exceptional non-linear properties. Consequently, the non-linear properties can be 100 or 1000 times as high as the non-linearity of silica. The presentation deals with the latest results in terms of optical properties and applications of chalcogenide glass fibers, including photonic crystal fibers and fibers for optical sensors. 1

Abstract

The paper illustrates the design and the optimization of a medium infrared (Mid-IR) microstructured fiber laser based on dysprosium doped chalcogenide glass, Dy3+:Ga 5 Ge 20 Sb 10 S 65 . The investigation is performed realistically, by taking into account the spectroscopic parameters measured on samples of the aforesaid glasses. The aim is to investigate the feasibility of optical beam generation close to 4.4 µm wavelength. An output power of 107.2 mW with an input pump power of 1 W is calculated. This result indicates that the designed laser configuration can lead to a feasible medium infrared source which could find application in optical free propagation, biomedicine and sensing.
