Abstract

Apart from gain dependence on polarization state, phase modulation in semiconductor optical amplifier (SOA) is usually polarization dependent as a result of birefringence. This paper analyzes the factors that determine the polarization dependence of phase modulation and proposes the necessity of fabricating SOA with polarization-insensitive gain and polarization-insensitive phase modulation. Based on energy band theory, the strain effects on polarization dependences of gain and differential refractive index in multiple quantum-well (MQW) SOA are studied, it is demonstrated that SOA with polarization insensitive gain and polarization insensitive phase modulation can be achieved by optimal design of active region and waveguide structure.
