COMBINED INFLUENCE OF DESIGN AND CARRIER SCATTERING ON THE ULTRAFAST EMISSION DYNAMICS OF QUANTUM-WELL MICROCAVITY LASERS

A microscopic theory for vertical-cavity surface-emitting lasers (VCSE Ls) with quantum-well active layers is applied to study the transient gain dynamics, nonequilibrium carrier effects and the influence of the laser design. We investigate how the laser response on femtosecond pu lse excitation can be controlled in terms of (i) excitation conditions of the VCSEL, (ii) the mirror design, which allows to change the cavi ty quality and the resonance frequency, and (iii) the number and posit ion of active semiconductor quantum-wells.
