Quasi-3D coupled electro-optical simulation of MQW avalanche waveguide photodetectors

摘要

The physics-based modeling of InAlAs/InGaAs waveguide MQW avalanche photodiodes is addressed through a coupled electro-optical quasi-3D approach, based on selfconsistent application of drift-diffusion simulation and the effective refractive index method. The application of the model to two recently proposed waveguide MQW APD structures shows a good agreement with experimental results.
