提高半导体激光器调制带宽的匹配补偿电路

A matched compensation circuit for increase in modulation bandwidth of semiconductor lasers

限制半导体激光器调制带宽的一个重要因素是它的高频电路参数．设计了一匹配补偿电路以降低该电路参数的影响，同时使半导体激光器和信号源之间实现阻抗匹配．实验结果证明。

An important factor limiting the modulation bnadwidth of a semiconductor laser is its high frequency circuit parameters. A matched compensation circuit is designed to reduce the effects of these circuit parameters and to realize impedance match between a signal source and a semiconductor laser. Theoretical analyses and experiments show that the modulation frerquency and bandwidth can be increased greatly.
