摘要	A lightwave communication system is disclosed in which an integrated receiver is realized as a distributed Bragg reflector (MQW-DBR) laser structure biased at or below threshold. The receiver functions simultaneously as a tunable filter, optical amplifier, photodetector, and, if desired, as an FSK discriminator. It is also disclosed that the lightwave receiver also is capable of half duplex operation as a lightwave transmitter using the same DBR laser structure. The disclosed receiver eliminates complex coupling of the many different element realized by the integrated, multifunction structure.
其他摘要	公开了一种光波通信系统，其中集成接收器被实现为偏置在阈值或低于阈值的分布式布拉格反射器（MQW-DBR）激光器结构。接收器同时用作可调谐滤波器，光放大器，光电探测器，并且如果需要，还可用作FSK鉴别器。还公开了光波接收器还能够作为使用相同DBR激光器结构的光波发射器的半双工操作。所公开的接收器消除了由集成的多功能结构实现的许多不同元件的复杂耦合。
