Wavelength converter based on cross-gain modulation in multi-electrode single-port-coupled semiconductor optical amplifier

提出了一种新型的基于多电极单端耦合半导体光放大器(SOA)的交叉增益调制(XGM)型波长转换方案,并建立了这种波长转换器完整的宽带理论模型.通过数值模拟的方法,比较了基于多电极单端耦合SOA的XGM型波长转换和基于单电极单端SOA的XGM型波长转换的输出特性,结果表明前者的输出消光比优于后者,而且啁啾特性也略有改善.

A new scheme for cross-gain modulation （XGM） wavelength converter based on multi-electrode single-port-coupled semiconductor optical amplifier （SOA） is proposed, and a comprehensive broad-band dynamic model of this kind of wavelength converter is presented. By numerical simulation, the output performances of two kinds of XGM wavelength converter based on multi-electrode single-port-coupled SOA and based on single-port-coupled SOA are investigated. The result shows that the extinction ratio of XGM wavelength converter based on multi-electrode single-port-coupled SOA is greater than that of the later.
