Characteristics of small signal gain spectrum and static gain saturation of integrated twin-guide semiconductor optical amplifier (ITG-SOA) are theoretically investigated and compared with those of SOA. A comprehensive ITG-SOA model is proposed to effectively extend the application range of previous models. The model considers the interaction between carrier density and photon density as well as the longitudinal variation of phase-match degree induced by input power. Two kinds of ITG-SOAs are expected to have different small signal amplification characteristics. The unique gain saturation characteristics of ITG-SOA, which have been well explained, show great promise in wavelength conversion: enhanced extinction ratio, reduced input pump power level, and quasi-digital response.
