New Modeling Approach for High Frequency Devices: Application to Ultrafast Optically Controlled Switches

In many ultrafast semiconductor devices, the effects of generated electromagnetic waves cannot be neglected. These devices can be accurately simulated by combining a direct finite difference time domain solution of Maxwell´s equations with a Bipolar Monte-Carlo model of semiconductor carrier transport. This approach is utilized to investigate the response of an electro-optic switch with a subpicosecond risetime. Discussion and results showing the effects of wave propagation will also be presented.
