摘要

为了便于制造，我们设计并制造了一种偏振无关的点尺寸转换器-半导体光放大器(SS-SOA)，使用宽矩形波导。通过在有源区使用分离约束异质结构(SCH)层来补偿有源区增益的极化依赖性和器件两侧SS区耦合效率的极化依赖性。SS-SOA具有低偏振依赖性、高增益、与光纤的高效耦合和均匀远场模式等高性能特性。

High gain and low polarization dependent 1.55-/spl mu/m semiconductor optical amplifier with a spot-size converter

We have designed and fabricated a polarization independent spot-size convertor-semiconductor optical amplifier (SS-SOA) using a wide rectangular waveguide for ease of fabrication. The polarization dependence of the gain in the active region and that of the coupling efficiency in the SS regions on both sides of the device are compensated together by using a separate-confinement heterostructure (SCH) layer in the active region. The SS-SOA exhibits high-performance characteristics, such as low polarization dependence, high gain, efficient coupling to fiber, and uniform far-field-patterns.
