摘　　要：从微腔半导体激光器速率方程出发，分析讨论了微腔激光器的脉码调制特性，发现微腔具有较规则的脉冲响应，可以减少误码率；自发发射因子为０．１的微腔，具有脉码率高达５０Ｇｂｉｔ／ｓ良好的调制眼图，微腔激光器在光互联中将有广泛的应用前景。模拟了以微腔激光器为光源的光纤通信系统，给出脉码率为１０Ｇｂｉｔ／ｓ传输不同距离的接收眼图，证明能够实现６０ｋｍ的传输。We have analyzed numerical code modulation of semiconductor microcavity lasers by using rate equations. It is found that microcavity lasers have high speed pulse code response and minimum error probability. An excellent eye diagram can be obtained with the microcavity lasers modulated by a 50 Gbit/s current if their spontaneous emission factors equal 0.1. The lasers will open vast vistas in future optical connection. Furthermore, we have simulated fiber communication systems with microcavity lasers as the light sources 10 Gbit/s numerical codes modulated and have given the received eye diagrams after transmission of different distances. It is proved that the system can stand for 60 kilometers′ transmission.
