Spin‐controlled lasers are highly interesting photonic devices and have been shown to provide ultrafast polarization dynamics in excess of 200 GHz. In contrast to conventional semiconductor lasers their temporal properties are not limited by the intensity dynamics, but are governed primarily by the interaction of the spin dynamics with the birefringent mode splitting that determines the polarization oscillation frequency. Another class of modern semiconductor lasers are high‐β emitters, which benefit from enhanced light–matter interaction due to strong mode confinement in low‐mode‐volume microcavities. In such structures, the emission properties can be tailored by the resonator geometry to realize for instance bimodal emission behavior in slightly elliptical micropillar cavities. This attractive feature is utilized to demonstrate and explore spin‐lasing effects in bimodal high‐β quantum dot micropillar lasers. The studied microlasers with a β‐factor of 4% show spin‐laser effects with experimental polarization oscillation frequencies up to 15 GHz and predicted frequencies up to about 100 GHz, which are controlled by the ellipticity of the resonator. These results reveal appealing prospects for very compact, ultrafast, and energy‐efficient spin‐lasers and can pave the way for future purely electrically injected spin‐lasers enabled by short injection path lengths.

Fluorescent microbeads are widely used for applications in life sciences and medical diagnosis. The spectral contrast and sharpness of photoluminescence are critical in the utilities of microbeads for imaging and multiplexing. Here, microbeads capable of generating single‐peak laser emission with a sub‐nanometer linewidth are demonstrated. The microbeads are made of quantum dots that are tightly packed and crosslinked via ligand exchange for high optical gain and refractive index as well as material stability. Bright single‐mode lasing with no photobleaching is achieved with particle diameters as small as 1.5 µm in the air. Sub‐nm lasing emission is maintained even inside high‐index surroundings, such as organic solvents and biological tissues. Feasibility of intracellular tagging and multi‐color imaging in vivo is demonstrated. [ABSTRACT FROM AUTHOR]

We report on the realization of a dense, large-scale array of 900 quantum dot micropillar cavities with high spectral homogeneity. We target applications in photonic information processing such as optical reservoir computing which can be implemented in large arrays of optically coupled microlasers. To achieve the required spectral homogeneity for the underlying optical injection locking, we calculate and set the diameter of each individual micropillar within the array during the fabrication process by taking the diameter-dependent emission wavelength of the microcavities into account. Using this kind of diameter adjustment, we improve the overall wavelength homogeneity in a 30 × 30 micropillar array by 64% and reduce the standard deviation of the resonance energy distribution by 26% from 352 μeV in the planar unprocessed sample to 262 μeV in the fabricated array. In addition, we present a detailed analysis of the device quality and the diameter control of the micropillar's emission wavelength, which includes important information for the effective application of the developed fabrication method for the realization of highly homogeneous micropillar arrays in the future.

All-color subwavelength output of lasers was demonstrated in a rationally designed organic microdisk/silver nanowire heterostructures. The dye-doped flexible microdisks served as the wavelength tunable whispering-gallery-mode lasers with low lasing thresholds, whereas the silver nanowires supported the output of the lasing mode as subwavelength coherent light sources. The wavelength of the outcoupled laser was tuned over the full visible spectrum scope owing to the flexibility of the microdisks and their compatibility with various organic laser dyes. Furthermore, a multicolor subwavelength laser was achieved in a single heterostructure and the laser output was successfully modulated by varying the surface plasmon polariton propagation length.

The thermal resistance of AlGaAs/GaAs microlasers of the suspended-disk type with a diameter of 1.7-4 μm and InAs/InGaAs quantum dots in the active region is inversely proportional to the squared diameter of the microdisk. The proportionality factor is 3.2 × 10 (K cm)/W, and the thermal resistance is 120-20°C/mW. [ABSTRACT FROM AUTHOR]

Nichtklassische Lichtquellen sind wichtige Komponenten für die zukünftige Realisierung von optischen Quantencomputern, Quantenkommunikationsnetzwerken und Anwendungen in der Quantenmetrologie. Besonders hervorzuheben sind Quantenlichtquellen auf der Basis von Halbleiter-Quantenpunkten zur Erzeugung von einzelnen ununterscheidbaren Photonen, Zwillingsphotonen-Zuständen oder polarisationsverschränkten Photonenpaaren. Zusätzlich erlaubt die fortgeschrittene Halbleitertechnologie die deterministische Integration einzelner Quantenpunkte in photonische Strukturen. In ähnlicher Weise sind quantenpunktbasierte Mikrosäulenlaser sowohl für die Grundlagenforschung auf dem Gebiet der Quantenelektrodynamik in Resonatoren als auch für zukünftige Anwendungen in der Datenübertragung aufgrund ihrer mikroskopischen Abmessungen, ihrer hohen Modulationsbandbreite und ihres geringen Energieverbrauchs von großem Interesse. Die Charakterisierung von Quantenemitter hinsichtlich ihrer Photonenstatistik wird in der Quantenoptik typischerweise durch die Messung der normalisierten Photonen-Autokorrelationsfunktion zweiter Ordnung g(2)(Ƭ) bestimmt, jedoch nur der vollständige Zugang zur Photonenzahlverteilung ermöglicht einen tieferen Einblick in die physikalischen Prozesse der Lichtentstehung. Vor diesem Hintergrund werden in der vor liegenden Arbeit erstmalig photonenzahlauflösende Detektoren zur Charakterisierung von quantenpunktbasierten nanophotonischen Strukturen verwendet. Die Detektoren sind supraleitende Übergangskantensensoren, die wiederum von supraleitenden Quanteninterferenzdetektoren ausgelesen werden. Zum Betrieb der Detektoren wird eigens ein adiabatischer Entmagnetisierungskryostat aufgebaut, um die Detektormodule auf eine Temperatur von 6 100mK zu kühlen. Die einzelnen Detektorkanäle besitzen eine Detektionseffizenz von > 87%. In einem nächsten Schritt wird das aufgebaute photonenzahlauflösende Detektorsystem zur Charakterisierung eines quantenpunktbasierten Mikrosäulenlasers eingesetzt. Zwei Detektorkanäle detektieren gleichzeitig die Lichtemission von zwei orthogonalen Komponenten der fundamentalen Emissionsmode eines bimodalen Mikrosäulenlasers. Das angewandte experimentelle Schema bietet dabei einen beispiellosen Zugang zur gemeinsamen Photonenzahlverteilung und ermöglicht einen tiefen Einblick in die Dynamik und Photonenstatistik der Modenkomponenten, die durch das gemeinsame Verstärkungsmedium gekoppelten sind. Insbesondere decken dabei die photonenzahlauflösenden Messungen eine optische Bistabilität der gegensätzlich korrelierten Modenkomponenten auf, die sich in einem zeitlichen Schalten zwischen kohärenter und thermischer Lichtemission äußert. Des Weiteren wird mit dem photonenzahlauflösenden Detektorsystem die direkte Messung von Zweiphotonen-Zuständen einer energetisch entarteten Quantenpunkt-Biexztion-Exziton-Kaskade möglich. Das Experiment motiviert dazu, diese spezielle Konfiguration der Biexziton-Exziton-Kaskade durch einen Abstimmmechanismus zur realisieren. Die gewählte Methode ist dabei die Veränderung der elektronischen Bandstruktur durch einen mechanischen Spannungsübertag auf das Quantenpunkt-Halbleitermaterial. Mit diesem Verfahren ist es ebenfalls möglich, die Bindungsenergie und die Feinstrukturaufspaltung nahezu aufzuheben, was zur Erzeugung verschränkter Photonen unabdingbar ist. In einem finalen Schritt werden Quantenpunkte in Mikrolinsen integriert, um die Photonenauskoppeleffizienz zu erhöhen. In Kombination mit der Methode des mechanischen Spannungsübertrags ermöglicht es die Herstellung einer spektral abstimmbaren, hocheffizienten Einzelphotonenquelle. Um die zukünftige Anwendung dieser Technologie beispielsweise zur Verschränkungsvertauschung in einem Quantenrepeaternetzwerk zu demonstrierten, wird die Möglichkeit aufgezeigt, die Emissionslinien verschiedener Quantenpunkte so zu verstimmten, dass sie sich in Resonanz zueinander befinden. Eine zusätzliche Implementierung eines elektro-optischen Regelmechanismus stabilisiert dabei die Emissionsenergie im Bereich der homogenen Linienbreite der Emitter., Non-classical light sources are important components for the future realization of optical quantum computers, quantum communication networks and applications in quantum metrology. Quantum light sources based on semiconductor quantum dots are predestinated for the generation of single indistinguishable photons, twin-photon states, or polarizationentangled photon pairs. A special benefit is the advanced semiconductor technology allows the deterministic integration of quantum dots into photonic structures. Equally interesting are quantum dot-based micropillar lasers, which are important for both fundamental research in the in the field of quantum electrodynamics in resonators as well as for future applications in data transmission, due to their microscopic dimensions their high modulation bandwidth and their low power consumption. Not only the development of more efficient quantum emitters, but also the metrology of these structures has become increasingly important. Understanding the underlying physical processes of light emission is typically achieved in quantum optics by measuring the normalized second-order autocorrelation function g(2)(Ƭ). A deeper insight into the light emitting process can be obtained by a full access to the photon-number distribution, which also enables to compute higher-order correlation functions. In this context, photon-number-resolving detectors are used for the first time to characterize quantum dot-based nanophotonic structures. The detectors are superconducting transition-edge sensors, which are read-out by superconducting quantum interference devices. To operate the detectors in a cryogenic environment, an adiabatic demagnetization refrigerator is installed. The detector modules for photon number detection are implemented on the coldest stage and are operated at a temperature of 100 mK. The detection efficiency of the individual channels is determined to >87%. In a next step, the photon-number-resolving detector system is used to characterize a quantum dot-based micropillar laser. Two detector channels simultaneously detect the light emission from two orthogonal components of the fundamental emission mode of the bimodal micropillar laser. The applied experimental scheme thereby provides unprecedented access to the joint photon-number distribution and provides a deep insight into the dynamics and photon statistics of the coupled modes due to the common gain medium. In particular the measurements reveal an optical bi-stability of the correlated mode components, which can be interpreted as a temporal switching between emission with coherent and thermal emission statistics. Furthermore, the photon number-resolving detector system is used to directly measure the two-photon states of an energetically degenerate biexciton-exciton cascade. The experiment motivates to use a tuning mechanism to achieve this special energy alignment. The chosen method is mechanical strain transfer to the quantum dot semiconductor material, which has an direct effect on the electronic band structure. With this method, it is also possible to tune the binding energy and the fine-structure splitting nearly to zero. In a final step, quantum dots are integrated into microlenses in order to increase the photon extraction efficiency. Subsequently, the method of mechanical strain tuning allows the fabrication of a spectrally tunable, highly efficient single-photon source. To demonstrate the scalability of the device concept for entanglement swapping experiments, the emission lines of three different quantum dots can be tuned in spectral resonance. An additional implementation of an electro-optical control mechanism stabilizes the emission energy in the range of the homogeneous linewidth of the emitters.

We report on electrically pumped quantum dot-microlasers in the presence of polarized self-feedback. The high-ß microlasers show two orthogonal, linearly polarized emission modes which are coupled via the common gain medium. This coupling is explained in terms of gain competition between the two lasing modes and leads to distinct differences in their input-output characteristics. By applying polarized self-feedback via an external mirror, we are able to control the laser characteristics of the emission modes in terms of the output power, the coherence time and the photon statistics. We find that linearly polarized self-feedback stabilizes the lasing of a given mode, while cross-polarized feedback between the two modes reduces strongly the intensity of the other emission mode showing particular high-intensity fluctuations and even super-thermal values of the photon autocorrelation function g(2) (τ) at zero delay. Measurements of g(2) (τ) under external feedback also allow us to detect revival peaks associated with the round trip time of the external cavity. Analyzing the damping and shape of the g(2) (τ) revival peaks by a phenomenological model provides us insight into the underlying physics such as the effective exciton lifetime and gain characteristics of the quantum dots in the active region of these microlasers.

This paper describes the modeling of quantum-dot lasers with the aim of assessing the conditions for stable cw dual-mode operation when the mode separation lies in the THz range. Several possible models suited for InAs quantum dots in InP barriers are analytically evaluated, in particular quantum dots electrically coupled through a direct exchange of excitation by the wetting layer or quantum dots optically coupled through the homogeneous broadening of their optical gain. A stable dual-mode regime is shown possible in all cases when quantum dots are used as active layer whereas a gain medium of quantum well or bulk type inevitably leads to bistable behavior. The choice of a quantum-dot gain medium perfectly matched the production of dual-mode lasers devoted to THz generation by photomixing. [ABSTRACT FROM AUTHOR]

CG and FJ gratefully acknowledge financial support from the German Science Foundation (DFG). FJ further acknowledges support from the German Federal Ministry of Education and Research (BMBF). Measured and calculated results are presented for the emission properties of a new class of emitters operating in the cavity quantum electrodynamics regime. The structures are based on high-finesse GaAs/AlAs micropillar cavities, each with an active medium consisting of a layer of InGaAs quantum dots and the distinguishing feature of having a substantial fraction of spontaneous emission channeled into one cavity mode (high β-factor). This paper demonstrates that the usual criterion for lasing with a conventional (low β-factor) cavity, that is, a sharp non-linearity in the input-output curve accompanied by noticeable linewidth narrowing, has to be reinforced by the equal-time second-order photon autocorrelation function to confirm lasing. The paper also shows that the equal-time second-order photon autocorrelation function is useful for recognizing superradiance, a manifestation of the correlations possible in high-β microcavities operating with quantum dots. In terms of consolidating the collected data and identifying the physics underlying laser action, both theory and experiment suggest a sole dependence on intracavity photon number. Evidence for this assertion comes from all our measured and calculated data on emission coherence and fluctuation, for devices ranging from light emitting diodes (LEDs) and cavity-enhanced LEDs to lasers, lying on the same two curves: one for linewidth narrowing versus intracavity photon number and the other for g(2)(0) versus intracavity photon number.

This work demonstrates the fabrication and optical characterization of polymeric whispering gallery mode lasers. For the realization of low threshold quantum dot- and organic dye lasers different integration techniques are presented. To further improve the polymer resonators for robust device applications, room temperature resonance mode control and tuning of the lasing modes, on scales compatible with on-chip integration, is introduced.

QUANTUM dots , *MICROLASERS - Abstract
The super-thermal photon bunching in quantum-dot (QD) micropillar lasers is investigated both experimentally and theoretically via simulations driven by dynamic considerations. Using stochastic multi-mode rate equations we obtain very good agreement between experiment and theory in terms of intensity profiles and intensity-correlation properties of the examined QD micro-laser’s emission. Further investigations of the time-dependent emission show that super-thermal photon bunching occurs due to irregular mode-switching events in the bimodal lasers. Our bifurcation analysis reveals that these switchings find their origin in an underlying bistability, such that spontaneous emission noise is able to effectively perturb the two competing modes in a small parameter region. We thus ascribe the observed high photon correlation to dynamical multistabilities rather than quantum mechanical correlations. [ABSTRACT FROM AUTHOR]
