半导体光开关工作电流和速率的理论分析

Analysis of Operating Current and Rate of Semiconductor Optical Waveguide Switch

本文从载流子连续性方程出发，采用半导体双异质结概念，从理论上推出了计算半导体光波导开关工作电流和速率的理论公式，为器件选取工作电流和提高开关速率提供了理论依据．

Based on the concept of double heterostructure and the charge-carrier continuintyequation, we present theoretical formula for switch rate and the operating current, whichprovides theoretical basis for choosing the operating current of switch and switch rate.
