利用光纤耦合输出反馈泵浦半导体激光双稳装置,实现了微分增益、双稳和零偏等三种工作模式的运转。由此完成了恒定偏置和脉冲偏置光信号放大、光脉宽压缩、限幅、整形和开关等多种光信号处理功能。光信号增益达22.5 dB,脉宽可压缩25倍。

Using an optical fiber-coupled semiconductor laser diode OBD with output feedback pumping, operations in 3 modes (differential gain, bistability, and zero-bias), have been realized respectively, and optical signal amplification, pulse-width compression, limiting, reshaping, and switching have been implemented. The optical gain is about 22.5 dB, and the compression ratio is about 25.
