Abstract

The feasibility of detecting the emission of a microdisk laser with a diameter of 23 μm with an active region based on InGaAs/GaAs quantum well-dots using a nearby photodetector (100 × 4000 μm) with a similar active region is demonstrated. For continuous lasing, a pump current of 20 mA, and a distance between the faces of the microlaser and the photodetector of about 100 μm, a photocurrent of ~10 μA was obtained, which corresponds to a photodetector sensitivity of ~0.9 μA/μW.

摘要

证明了使用附近的具有相似有源区的光电探测器（100×4000μm）检测具有InGaAs / GaAs量子阱点的有源区，直径为23μm的微盘激光器发射的可行性。对于连续激射，20 mA的泵浦电流以及微激光器的表面与光电探测器之间的距离约为100μm，可获得〜10μA的光电流，这对应于〜0.9μA/μW的光电探测器灵敏度。
