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 ultrafast all-optical decoder scheme based on four-wave mixing (FWM) effect in semiconductor optical amplifier (SOA) is proposed. In the scheme, Polarization Shift Keying (Polarization-shift-keying, PolSK) signal light.A complete polarization-dependent broadband theoretical model of this all-optical decoder is established considering the polarization dependence of SOA.Finally, by means of numerical simulation, Optical decoder, and studies the influence of the optical power of two input signals, the SOA injection current and the polarization dependence of SOA on the output characteristics of all optical decoders.
