A lumped element electrical equivalent circuit model for traveling-wave semiconductor optical amplifier (TW-SOA) has been developed. The model is compatible with large signal analysis for both optical and current modulation. The novelty of this circuit model is the inclusion of wavelength dependency of gain of SOA over our earlier reported work. The paper describes dynamic response of SOA for both...
This paper presents an equivalent lumped element electric circuit model for traveling wave semiconductor optical amplifier (SOA) in integrated circuit applications. The model facilitates incorporation of chip and package parasitic elements of SOA. The model is used to represent an all optical 2 × 2 switch based on cross gain modulation in SOA capable of operating at an ultra fast speed. SPICE simulation...
