Abstract

Summary form only given. High linearity semiconductor optical amplifiers (SOAs) are important for 1.3 μm single-channel CATV amplifiers in (WDM) system applications. The amplification nonlinearity or crosstalk between channels are caused by gain nonlinearity generated from the gain compression effect. We have considered important design factors which can affect the gain linearity of an SOA. Device concepts based on current injection profile are proposed and numerically demonstrated to achieve gain and less crosstalk
