Abstract

We present a novel self-consistent time-domain model for the analysis and design of traveling-waveelectroabsorption modulators (TW-EAMs). The model fully accounts for the nonlinear interaction betweenthe microwave and optical traveling fields. The effects on the bandwidth and modulation efficiency of the nonuniform optical field distribution along the device are discussed. A few examples of application are presented, showing the model to be an efficient tool for the analysis, design and optimization of TW-EAMs for analog and digital applications.
