集成双波导半导体光放大器小信号放大纵向特性
Longitudinal characteristics under small signal amplification of integrated twin-guide semiconductor optical amplifiers
摘要
Abstract
In order to investigate the longitudinal characteristics under small signal amplification of an integrated twin-guide semiconductor optical amplifier ( ITG-SOA) , a comprehensive ITG-SOA static model was utilized for analysis. Theoretical analysis reveals the optical power transfer between the active and passive waveguides of ITG-SOA is periodic and complete. Differing prominently from the decreasing monotonously of the carrier density along the propagation direction in SOA, the carrier density in the active waveguide of ITG-SOA swings periodically, whose amplitude increases gradually along the propagation direction. The normalized layer thickness, effective refractive index and longitudinal propagation constant in the active waveguide also present particular longitudinal distribution. This result is helpful for deeply understanding the working mechanism of ITG-SOA under small signal amplification.关键词
