| 摘 要： | 提出了一种新型的基于半导体光放大器（semiconductor optical amplifier, SOA）中四波混频（four-wave mixing, FWM）效应的超快全光译码器方案，方案中采用了偏振移位键控（polarization-shift-keying, PolSK）信号光.考虑SOA的偏振相关性，建立了这种全光译码器完整的偏振相关宽带理论模型.通过数值模拟的方法，从理论上实现了超快全光译码器，并研究了两输入信号光功率、SOA注入电流和SOA的偏振相关性对全光译码器输出特性的影响.关键词：全光译码器偏振移位键控四波混频半导体光放大器

| Abstract: | A novel scheme for ultrahigh-speed all-optical encoder based on four-wave mixing （FWM） in semiconductor optical amplifiers （SOAs） with PolSK modulated signals is proposed. Considering the polarization dependency of SOA, a comprehensive polarization-dependent broad-band dynamic model is presented. By numerical simulation, this kind of all-optical encoder is theoretically realized, and the effects of two input signal powers, injected current, and polarization dependency of SOA on the output performance of the encoder are analyzed. |
