| 1 | Emission from quantum-dot high-β microcavities: transition from spontaneous emission to lasing and the effects of superradiant emitter coupling显示文摘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(QDs)and the distinguishing feature of having a substantial fraction of spontaneous emission channeled into one cavity mode(highβ-factor).This paper demonstrates that the usual criterion for lasing with a conventional(lowβ-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-βmicrocavities operating with QDs.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. | Sören Kreinberg Weng W Chow Janik Wolters Christian Schneider Christopher Gies Frank Jahnke Sven Höfling Martin Kamp Stephan Reitzenstein 无 | 2017 | Light(Science & Applications)2017，6，1： | 2 |

| 17 | 3D printed micro-optics for quantum technology:Optimised coupling of single quantum dot emission into a single-mode fibre显示文摘Future quantum technology relies crucially on building quantum networks with high fidelity.To achieve this challenging goal,it is of utmost importance to connect individual quantum systems such that their emitted single photons overlap with the highest possible degree of coherence.This requires perfect mode overlap of the emitted light from different emitters,which necessitates the use of single-mode fibres.Here,we present an advanced manufacturing approach to accomplish this task.We combined 3D printed complex micro-optics,such as hemispherical and Weierstrass solid immersion lenses,as well as total internal reflection solid immersion lenses,on top of individual indium arsenide quantum dots with 3D printed optics on single-mode fibres and compared their key features.We observed a systematic increase in the collection efficiency under variations of the lens geometry from roughly 2 for hemispheric solid immersion lenses up to a maximum of greater than 9 for the total internal reflection geometry.Furthermore,the temperature-induced stress was estimated for these particular lens dimensions and results to be approximately 5 meV.Interestingly,the use of solid immersion lenses further increased the localisation accuracy of the emitters to less than 1 nm when acquiring micro-photoluminescence maps.Furthermore,we show that the single-photon character of the source is preserved after device fabrication,reaching a g^((2))(0)value of approximately 0.19 under pulsed optical excitation.The printed lens device can be further joined with an optical fibre and permanently fixed.This integrated system can be cooled by dipping into liquid helium using a Stirling cryocooler or by a closed-cycle helium cryostat without the necessity for optical windows,as all access is through the integrated single-mode fibre.We identify the ideal optical designs and present experiments that demonstrate excellent high-rate single-photon emission. | Marc Sartison Ksenia Weber Simon Thiele Lucas Bremer Sarah Fischbach Thomas Herzog Sascha Kolatschek Michael Jetter Stephan Reitzenstein Alois Herkommer Peter Michler Simone Luca Portalupi Harald Giessen | 2021 | Light(Advanced Manufacturing)2021，2，2： | 1 |

| 19 | Direct Comparison of Catalyst-Free and Catalyst-Induced GaN Nanowires显示文摘GaN nanowires have been grown by molecular beam epitaxy either catalyst-free or catalyst-induced by means of Ni seeds.Under identical growth conditions of temperature andⅤ/Ⅲratio,both types of GaN nanowires are of wurtzite structure elongated in the Ga-polar direction and are constricted by M-plane facets.However,the catalyst-induced nanowires contain many more basal-plane stacking faults and their photoluminescence is weaker.These differences can be explained as effects of the catalyst Ni seeds. | Caroline Chèze Lutz Geelhaar Oliver Brandt Walter M.Weber Henning Riechert Steffen Münch Ralph Rothemund Stephan Reitzenstein Alfred Forchel Thomas Kehagias Philomela Komninou George P.Dimitrakopulos Theodoros Karakostas | 2010 | Nano Research2010，3，7： | 0 |
| 20 | Quantum-optical spectroscopy of a twolevel system using an electrically driven micropillar laser as a resonant excitation source显示文摘Two-level emitters are the main building blocks of photonic quantum technologies and are model systems for the exploration of quantum optics in the solid state.Most interesting is the strict resonant excitation of such emitters to control their occupation coherently and to generate close to ideal quantum light,which is of utmost importance for applications in photonic quantum technology.To date,the approaches and experiments in this field have been performed exclusively using bulky lasers,which hinders the application of resonantly driven two-level emitters in compact photonic quantum systems.Here we address this issue and present a concept for a compact resonantly driven single-photon source by performing quantum-optical spectroscopy of a two-level system using a compact high-βmicrolaser as the excitation source.The two-level system is based on a semiconductor quantum dot(QD),which is excited resonantly by a fiber-coupled electrically driven micropillar laser.We dress the excitonic state of the QD under continuous wave excitation,and trigger the emission of single photons with strong multi-photon suppression(ge2Te0T?0:02)and high photon indistinguishability(V=57±9%)via pulsed resonant excitation at 156 MHz.These results clearly demonstrate the high potential of our resonant excitation scheme,which can pave the way for compact electrically driven quantum light sources with excellent quantum properties to enable the implementation of advanced quantum communication protocols. | Sören Kreinberg Tomislav Grbešić Max Strauß Alexander Carmele Monika Emmerling Christian Schneider Sven Höfling Xavier Porte Stephan Reitzenstein | 2018 | Light(Science & Applications)2018，7，1： | 0 |
