摘要

在这项工作中，我们研究了单行载波光电二极管(PD)的不同特性通过器件的数学建模。基于数学模型中包含的基本电路元件，建立了UTC-PD的等效电路模型。频率响应和脉冲光电流响应与报道的数据吻合较好。笔者认为，这种UTC光电二极管的电路模型在其他地方尚未见报道。研究了不同参数和器件安装寄生效应对频率响应的影响。这种简化的电路模型将有助于在UTC光电二极管制造前预测其不同特性。

Equivalent circuit model of UTC photodiode

In this work we have examined different characteristics of uni travelling carrier (UTC) photodiode (PD) by mathematical modeling of the device. Based on the basic circuit elements contain in the mathematical model, an equivalent circuit model of UTC-PD is developed. The frequency response and pulse photocurrent response agrees well with reported data. To the authors believe such kind of circuit model of UTC photodiode has not been reported elsewhere. The influences of different parameters and device mounting parasitic effects on frequency response have been investigated. Such simplified circuit model will be helpful in predicting different characteristics of UTC photodiode before fabrication.
