摘要

本文对BC型激光二极管（LD）从理论上导出弛豫振荡频率公式

并在实验上得到了验证.研制出高速LD组件

其调制频率可以达到5.3GHz.并在一公里光纤链路上测量了检测信号的载噪比、互调失真等特性.结果表明:该LD组件可用于直接传输C波段卫星下行信号（3.7～4.2GHz）的副载波复用光纤通信系统.

Abstract

In this paper

the relaxation frequency formula of the BC laser diode （LD） is theoretically derived

and confirmed experimentally. The high-speed LD module has been built which has broadband modulation property up to 5.3GHz. By using this LD module in 1km optic fiber link

the other properties are measured. It is suitable to transmit C band signal （3.7- 4. 2GHz） from communication satellite into the subcarrier multiplex optical fiber communication system.
