Abstract
An experimental and theoretical study of carrier dynamics in quantum well optical amplifiers is presented. Experimentally, the dynamics is studied using a pump-and-probe technique employing ultrashort optical pulses. The theoretical model is based on semi-classical density matrix equations. The effects of spectral holeburning, carrier heating, carrier transport (diffusion), and carrier capture are considered. Characteristic temperature relaxation and carrier capture times due to carrier-phonon scattering are calculated based on a unified treatment.
