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.
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.
