SPICE model for microwave properties of traveling-wave electroabsorption modulators

We present a circuit model of TW-EAM to analyze electrical and optical characteristics of traveling-wave electroabsorption modulators (TW-EAMs) using SPICE simulation. We consider the interaction between electromagnetic fields and optical powers in waveguides to model electrical and optical behaviors of TW-EAMs. The effects of microwave properties of waveguides on modulation response and output optical power of TW-EAMs are analyzed by the proposed model.
