Abstract
The author discusses simulation of time-resolved pump and probe experiments in which an ultrafast optical pulse is used to generate interband transitions within the solid. Subsequent time-delayed optical spectra are taken as a probe of the photoexcited carrier distribution as it relaxes back to an equilibrium state. In an ensemble Monte Carlo simulation, the stochastic motion of various quasi-particles (electrons, holes, phonons, photons, etc.) subject to scattering is modeled dynamically. This procedure has been used successfully to show the importance of nonequilibrium hot phonons in the long-time constant cooling of a photoexcited electron-hole plasma, the effect of intervalley transfer on the relaxation time in GaAs and InP, and the influence of intercarrier scattering on low- and high-energy excitation in quantum wells and bulk and on intersubband relaxation in quantum wells.
