M. Grupen et K. Hess, SELF-CONSISTENT CALCULATION OF THE MODULATION RESPONSE FOR QUANTUM-WELL LASER-DIODES, Applied physics letters, 65(19), 1994, pp. 2454-2456
Modulation responses for a set of strained-layer InGaAs quantum well l
asers as calculated by a new version of Minilase are presented and com
pared to experiment. Based upon the agreement with measured data, Mini
lase is used further to associate gain saturation and low frequency ro
lloff with carrier capture in the quantum well. The capture rates, the
refore, influence the modulation response in a significant way even if
the time constants are much shorter than the inverse frequency of the
modulation signal. (C) 1994 American Institute of Physics.
