Abstract

Photodiodes based on solid solutions in the GaSb–InAs system are for the first time applied to study the spectral characteristics of single and coupled whispering-gallery-mode (WGM) lasers emitting in a range of 2.2–2.3 μm. The capacity of photodiodes with a photosensitive area 2.0 mm in diameter is C = 520 pF at U = –2 V, which corresponds to a time constant of τ = 53 ns. It is shown that the parameters of the fabricated photodiodes make it possible to detect the emission of quantum-sized disc lasers at room temperature not using cryogenic cooling.

摘要

GaSb–InAs系统中基于固溶体的光电二极管首次用于研究单和耦合的耳语画廊模式（WGM）激光器在2.2–2.3μm范围内发射的光谱特性。在U = –2 V时，直径为2.0 mm的感光区域的光电二极管的容量为C = 520 pF ，对应于时间常数τ= 53 ns。结果表明，所制造的光电二极管的参数使得可以在不使用低温冷却的情况下，在室温下检测量子尺寸的光盘激光器的发射。
