Abstract

A numerical simulation of the optical properties of a novel In_xGa_1-xAs/ In_1-yAl_yAs multiple quantum well heterostructure with tunable charge density is presented. The influence of carriers and dopant ion charges on the electronic properties is simulated by a self-consistent Poisson-Schrodinger solver. The calculated optical constants of the quantum well reproduce well the experimental data. It appears that this model can easily be implemented to include current injection and used as a design tool to optimize the performance of optical modulator quantum well devices.
