摘要
文章提出了一种利用半导体光放大器(SOA)中的四波混频(FWM)效应、适用于偏振移位键控(PolSK)调制的全光波长转换器方案。注入的辅助光可以缩短SOA增益恢复时间,增大饱和功率,提高波长转换效率。通过数值模拟从理论上实现了这种全光波长转换器,研究了输入泵浦光、信号光和辅助光功率对全光波长转换器输出特性的影响。
Abstract
An all-optical wavelength converter scheme appropriate for Polarization-Shift-Keying (PolSK) is proposed on the basis of the Four-Wave Mixing (FWM) effects in Semiconductor Optical Amplifiers (SOA). Injecting complementary light can shorten SOA gain recovery time, while amplifying saturated power improves the wavelength converting efficiency. This all-optical wavelength converter is theoretically implemented in numerical simulation and the effects of input pump light, signal light and complimentary light on the output properties of the converter are investigated.
