High Intensity Light Propagation In InAs (Postprint)

Abstract

We present our experimental and theoretical results on nonlinear absorption of light in InAs. The nonlinear variation of output intensity as a function of input intensity and time are calculated by solving four coupled rate equations simultaneously. All required quantities, including two-photon absorption, free-carrier absorption, Auger and radiative recombination lifetimes, and intrinsic carrier densities, have been obtained from the underlying bandstructures. The calculated thickness and energy-dependent output intensities in InAs agree very well with the values measured in our pump-probe experiments.
