Full Wave Electromagnetics for Simulating Terahertz Quantum Well Laser Diode Modulation

A unique discretization scheme that couples Maxwell's full wave vector field equations self-consistently with nonlinear charge and energy transport is presented. The scheme is used to simulate how terahertz modulation bandwidths may be achieved in a simple electrically pumped quantum well laser diode by dynamically heating the degenerate quantum charge gases with high frequency radiation.
