我们提出了一种新型的紧凑型纳米光子器件，由单片集成和电驱动的量子点（QD）微激光器激发的非经典光源组成。我们的器件概念是基于嵌入在微柱腔中的自组装InAs量子点，在量子通信和基于量子光学的信息处理领域具有许多潜在的应用。电驱动的微柱作为回音壁模式微激光器可在连续和脉冲模式下操作，具有520 ps的窄脉冲宽度和观察到的低至160 ps的衰减常数。这些微激光器被用作芯片上的激发源，以横向激发附近微柱中的单个QD，这些微柱又充当垂直发射的非经典光源。我们的紧凑型固态平台利用腔量子电动力学效应在连续和脉冲操作中产生反聚束光，g（2）CW（0）= 0.76 ± 0.03和g（2）Pulsed（0）= 0.78 ± 0.11，展示了其在高度集成芯片中产生触发单光子的潜力。
We present a novel compact nanophotonic device consisting of a nonclassical light source excited by a monolithically integrated and electrically driven quantum dot (QD) microlaser. Our device concept is based on self-assembled InAs QDs embedded in micropillar cavities and has many potential applications in the fields of quantum communication and quantum optics-based information processing. Electrically driven micropillars act as whispering gallery mode microlasers operable in both continuous and pulsed mode, with narrow pulse widths of 520 ps and decay constants as low as 160 ps observed. These microlasers are used as on-chip excitation sources to laterally excite individual QDs in nearby micropillars, which in turn act as vertically emitting nonclassical light sources. Our compact solid-state platform utilizes cavity-quantum electrodynamic effects to create antibunched light in continuous and pulsed operation with g(2)CW(0) = 0.76 ± 0.03 and g(2)Pulsed(0) = 0.78 ± 0.11, demonstrating its potential for the generation of triggered single photons in a highly integrated chip.
