Multimode emission and optical power in a semiconductor quantum dot laser.

Abstract

Effect of spatial hole burning (SHB) and multi-longitudinal-mode generation on high power operation of a quantum dot (QD) laser is studied. We use a set of rate equations for confined carriers in QDs, free carriers in the optical confinement layer and photons. The threshold currents and output powers of modes are computed numerically. The power of the main… (More)
