On the High Speed Modulation Bandwidth of Quantum Well Lasers

Abstract

A recent formulation of the gain in conventional three-dimensional double heterostructure (DH) and two-dimensional quantum well (QW) semiconductor lasers has been used to study the high speed modulation in such lasers. The emphasis is on the differential gain and nonlinear (i.e., intensity dependent) gain suppression in these material systems. We conclude that,in variance with earlier predictions, the expectation of higher modulation speed in QW lasers is not warranted at room temperature. The advantage of using multiple QW structure for high speed performance has been analyzed.
