基于半导体光放大器的暗脉冲的产生
Generation of Dark Pulse Based on Semiconductor Optical Amplifier
摘要
采用基于半导体光放大器(SOA)的“8”字腔激光器结构，当SOA的驱动电流是220 mA时，通过调整腔内的偏振控制器(PC)，产生脉冲宽度分别是74 ns和20 ns，重复频率分别是9 MHz(基频)和33.4 MHz(二倍频)的暗脉冲。改变SOA在非线性放大环镜(NALM)中的位置，暗脉冲的脉宽也有相应的改变。
Abstract
In the experiment of laser based on semiconductor optical amplifier (SOA), when the drive current of the SOA is up to 220 mA, by adjusting the polarization controller (PC), dark pulse is observed. The pulse durations are 74 ns and 20 ns with frequency repetition rates of 9 MHz (fundamental frequency) and 33.4 MHz (double frequency), respectively. By changing the position of the SOA in the nonlinear amplifying loop mirror (NALM), dark pulse width change accordingly.
