- Abstract
Les fibres optiques microstructurées, également appelées fibres à trous ou fibres optiques à cristal photonique sont un type récent de guides de lumières originaux et performants apparues dans le milieu des années 1990. Elles se sont depuis imposées comme une technologie incontournable de la photonique moderne. L’originalité première de ce genre de fibre a été de permettre le guidage de la lumière dans un matériau unique grâce à leur structuration périodique. Après une vingtaine d’années de recherche, la gamme possible de structures de ces fibres optiques s’est grandement étoffée, donnant lieu à plusieurs catégories de fibres microstructurées classifiées par type de mécanisme de guidage (par réflexion totale interne, par bande interdite photonique, et par couplage inhibé). Arrivées à maturité aujourd’hui, ces fibres optiques ont démontré au fil des années un potentiel d’applications extrêmement vaste et ce, dans des domaines très variés allant de la défense aux applications biophotoniques, sous la forme de capteurs optiques ou de lasers fibrés de forte puissance.

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.

International audience; Up to 16 dB frequency noise reduction and a linewidth 8 times narrower that of the pump source is reported for the Stokes component in a compact Brillouin fiber laser made of chalcogenide microstructured fiber. Since the pump wave is not resonant in the ring cavity, an active stabilization of the laser is not primordial thus making the system simpler and cheaper. Although only a 3 metre-long microstructured chalcogenide fiber was used as gain medium, a very low laser threshold power of 6 mW was obtained for nonresonant pumping. The linewidth-narrowing effect achieved in our BFL cavity is also discussed.

International audience; A highly birefringent polarization-maintaining chalcogenide microstructured optical fiber (MOF) covering the 3-8.5 µm wavelength range has been realized for the first time. The fiber cross-section consists of 3 rings of circular air holes with 2 larger holes adjacent to the core. Birefringence properties are calculated by using the vector finite-element method and are compared to the experimental ones. The group birefringence is 1.5x10−3 and fiber losses are equal to 0.8 dB/m at 7.55 µm.

A low-loss suspended core As38Se62 fiber with core diameter of 4.5 μm and a zero-dispersion wavelength of 3.5 μm was used for mid-infrared supercontinuum generation. The dispersion of the fiber was measured from 2.9 to 4.2 μm and was in good correspondence with the calculated dispersion. An optical parametric amplifier delivering 320 fs pulses with a peak power of 14.8 kW at a repetition rate of 21 MHz was used to pump 18 cm of suspended core fiber at different wavelengths from 3.3 to 4.7 μm. By pumping at 4.4 μm with a peak power of 5.2 kW coupled to the fiber a supercontinuum spanning from 1.7 to 7.5 μm with an average output power of 15.6 mW and an average power >5.0 μm of 4.7 mW was obtained.

In this paper, photodarkening (PD) and photobleaching (PB) impact on 1030 nm ytterbium doped fiber laser emission are presented. In comparison with 1070 nm fiber laser built from the same kind of aluminosilicate fiber, the 1030 nm fiber laser shows less PD loss as the consequence of lower inversion and the possibility of almost complete efficiency recovery obtained by 633 nm PB. The results indicate the importance of inversion in PD process rather than photons interplay with the phenomenon as well as the occurrences of lower energy de-activation defects.

We theoretically demonstrate a novel approach for generating Mid-InfraRed SuperContinuum (MIR SC) by using concatenated fluoride and chalcogenide glass fibers pumped with a standard pulsed Thulium (Tm) laser (TFWHM=3.5ps, P0=20kW, νR=30MHz, and Pavg=2W). The fluoride fiber SC is generated in 10m of ZBLAN spanning the 0.9–4.1μm SC at the −30dB level. The ZBLAN fiber SC is then coupled into 10cm of As2Se3 chalcogenide Microstructured Optical Fiber (MOF) designed to have a zero-dispersion wavelength (λZDW) significantly below the 4.1μm InfraRed (IR) edge of the ZBLAN fiber SC, here 3.55μm. This allows the MIR solitons in the ZBLAN fiber SC to couple into anomalous dispersion in the chalcogenide fiber and further redshift out to the fiber loss edge at around 9μm. The final 0.9–9μm SC covers over 3 octaves in the MIR with around 15mW of power converted into the 6–9μm range.

A set of Ce-/Yb-co-doped silica optical fiber preform cores, differing in terms of dopant concentrations are studied by Electron Paramagnetic Resonance (EPR) spectroscopy before and after irradiation of the samples with excimer UV laser light and γ-rays. Evidence of Yb3 + clustering in the case of high Yb content samples is observed on as prepared samples regardless of the presence of Ce3 + ions. Si-E′ and Al-OHC centers were identified upon photon irradiation. The results are correlated to the micro-structural origin of the photodarkening process occurring in Ce–Yb doped glass fibers.

In this letter, we investigate the impact of a 405 nm radiation on photodarkening generation in Yb- doped fiber laser. Simultaneous photodarkening and photobleaching effects induced by 976 and 405 nm radiations, respectively, were investigated in a 1070 nm laser and compared with the loss induced in an irradiated active fiber. We observed a significant photobleaching effect due to 405 nm radiation but not a complete recovery. A strong absorption of the 405 nm radiation by the excited ions was also observed and could be the limiting factor for the bleaching performance. We also observed for the first time, to the best of our knowledge, ground-state absorption induced photodarkening in pristine fiber irradiated at 405 nm. This effect could generate additional residual losses in the laser system.

In this work, the influence of photodarkening (PD) and photobleaching (PB) on the lasing features of the ytterbium-doped aluminosilicate fiber lasers is examined. Simultaneous PD and PB with 633 nm irradiation was monitored at the lasing wavelength of 1070 nm and compared with individually caused PD and PB effects. The variation of laser threshold and slope efficiency was reported. By analyzing the laser performances it was found that the ratio of excess loss at 633 and 1070 nm is expected to be less than 20. In addition, considerable mitigation of the PD with 633 nm light irradiation is demonstrated.

A compact second-order Stokes Brillouin fiber laser made of microstructured chalcogenide fiber is reported for the first time. This laser required very low pump power for Stokes conversion: 6 mW for first order lasing and only 30 mW for second order lasing with nonresonant pumping. We also show linewidth-narrowing as well as intensity noise reduction for both the 1st and 2nd order Stokes component when compared to that of the pump source.

In this paper, an all-ber Brillouin laser ring cavity using a 3-m-long suspended-core chalcogenide As 38 Se 62 beris reported for the rst time to our knowledge. For a nonresonant ring cavity with no servo-locking, a laserthreshold power of 37 mW and an eciency of 26 % were obtained for a ber having a core diameter of 5 µ m.The linewidth of the Brillouin ber laser and the pump laser were respectively measured to be below 4 kHz,the resolution of our autocorrelator, and 250 kHz, thus showing the linewidth-narrowing nature of the Brillouinlaser. This result paves the way to compact Brillouin lasers with low threshold power and good spectral purity.A full experimental Brillouin characterization is also reported. We measured a Brillouin gain spectrum of 14.2MHz, a Brillouin gain coecient of 5.6 × 10 9 m/W and a Brillouin frequency shift of 7.95 GHz in our ber.Keywords: Stimulated Brillouin scattering; chalcogenide ber; Brillouin gain coecient; Brillouin gain spec-trum; suspended-core ber; Brillouin ber laser.

In this paper we report and summarize an extensive investigation of photodarkening in Yb-doped silica fibers. We made a set of similar fibers in order to cover a large Yb concentration range. The results show that once uniform inversion is reached all along the test fiber it is possible to show self-similarity of the time evolutions. The stretching parameter has a little influence. We can therefore provide two unique numbers to define photodarkening performance: the saturation loss and the time scale parameter. We also propose a possible figure of merit to compare different fibers. This may allow to evaluate the impact of photodarkening on laser/amplifier devices.

International audience; We compare, thanks to a Sagnac interferometer, the phase sensitivity to strain of different microstructured optical silica fibers (MSF) that we design and fabricate. Our results show that when a same elongation is applied to different MSF, the induced phase change is equal or lower than the one obtained for a standard fiber, showing no advantage on this parameter for sensing applications.

We report here the first demonstration of a mode-locked fiber laser delivering parabolic pulses (similaritons) at 1534 nm. The use of a Raman-based gain medium potentially allows its implementation at any wavelength. The 22nJ output similariton pulses have a true parabolic shape both in the time and spectral domains and a linear chirp. Linear recompression close to Fourier limit is demonstrated allowing us to obtain 6 ps compressed pulses with a compression factor of 75.

We present approximate but nevertheless highly accurate self-similar solutions to the generalized linear Schrodinger Equation appropriate to the description of pulse propagation in an optical fibre under the influence of distributed dispersion and gain or attenuation. These new similariton solutions apply for any shape of linearly chirped pulse for any dispersion and gain profiles and are indistinguishable from numerically generated solutions in the majority of practical applications.

The present work describes photodarkening from the viewpoint of cooperative luminescence. The temporal evolution of both effects was measured simultaneously by means of ytterbium doped aluminosilicate fibers for concentrations up to 1.8 wt% Yb3+. The quadratic dependence of photodarkening and cooperative luminescence versus dopant concentration was observed. The change in the photodarkening and cooperative luminescence mutual dynamics for highly and low doped fibers is ascribed to a different ion number which forms the cluster. Cooperative luminescence is proved to be a natural probe for photodarkening since it provides new pieces of information and contributes to the photodarkening mechanism description.

We report on an extensive investigation of photodarkening in Yb-doped silica fibers. A set of similar fibers, covering a large Yb concentration range, was made so as to compare the photodarkening induced losses. Careful measurements were made to ensure equal and uniform inversion for all the tested fibers. The results show that, with the specific set-up, the stretching parameter obtained through fitting has a very limited variation. This gives more meaning to the fitting parameters. Results tend to indicate a square law dependence of the concentration of excited ions on the final saturated loss. We also demonstrate self-similarity of loss evolution when experimental curves are simply normalized to fitting parameters. This evidence of self-similarity also supports the possibility of introducing a preliminary figure of merit for Yb-doped fiber. This will allow the impact of photodarkening on laser/amplifier devices to be evaluated.

International audience; Microstructured optical fibers (MOFs) are traditionally prepared using the stack and draw technique. In order to avoid the interfaces problems observed in chalcogenide glasses, we have developed a new casting method to prepare the chalcogenide preform. This method allows to reach optical losses around 0.4 dB/m at 1.55 µm and less than 0.05 dB/m in the mid IR. Various As(38)Se(62) chalcogenide microstructured fibers have been prepared in order to combine large non linear index of these glasses with the mode control offered by MOF structures. Small core fibers have been drawn to enhance the non linearities. In one of these, three Stokes order have been generated by Raman scattering in a suspended core MOF pumped at 1995 nm.

Topic: Fiber Optics and Optical Communications; International audience; We report significant advances in the fabrication of low loss chalcogenide microstructured optical fiber (MOF). This new method, consisting in molding the glass in a silica cast made of capillaries and capillary guides, allows the development of various designs of fibers, such as suspended core, large core or small core MOFs. After removing the cast in a hydrofluoric acid bath, the preform is drawn and the design is controlled using a system applying differential pressure in the holes. Fiber losses, which are the lowest recorded so far for selenium based MOFs, are equal to the material losses, meaning that the process has no effect on the glass quality.
