In gain-coupled (GC) multiple-quantum-well (MQW) distributed feedback (DFB) lasers, phenomena on the submicron scale corresponding to quantum-well active regions with etched Bragg gratings have been shown to affect overall laser performance. In this paper we present results combining submicron bi-dimensional modeling with a fine-scale longitudinal transfer(More)
Gain-coupled DFB lasers have a complicated modal interaction influenced by the effects of spatial hole burning (SHB) and nonlinear gain compression (NGC) because of the carrier dependent longitudinally distributed structures. In order to obtain a better understanding of the high single mode performance of gain-coupled DFB lasers, we perform a(More)
