Abstract

A model is proposed that makes it possible to analytically analyze the speed performance of a waveguide p–i–n photodiode with a light-absorbing region representing a multilayered array of quantum dots separated by undoped spacers. It is shown that there is an optimal number of layers of quantum dots, as well as an optimal thickness of the spacers, which provide the widest bandwidth. The possibility of achieving a frequency range (at the level of –3 dB) above 20 GHz for waveguide photodiodes based on InGaAs/GaAs quantum well-dots is shown.

量子点波导光电二极管速度性能模型

摘要本文提出了一个模型，可以对波导 pi-i-n 光电二极管的速度性能进行分析，该二极管的光吸收区为多层量子点阵列，中间用未掺杂的间隔物隔开。研究表明，量子点的最佳层数和间隔物的最佳厚度都能提供最宽的带宽。结果表明，基于 InGaAs/GaAs 量子点的波导光电二极管的频率范围（-3 dB 级）有可能超过 20 GHz。
