Abstract

Ultrafast lasers have been used along with electro-optic sampling techniques to characterize photoconductive switching devices and create transient waveforms with sub-picosecond rise times. We study these fast transients by coupling a three dimensional solution of Maxwell’s equations in the time domain with a bipolar Ensemble Monte Carlo model. Physical parameters of interest can be accurately computed and directly related to the measured data. We find that a proper inclusion of absorbing boundary conditions and details of the electro-optic material are crucial to transient velocity overshoot calculations.
