Abstract

In this paper, we analyze the effects of non-homogeneous carrier distributions in both the transverse and the longitudinal directions of multiple-quantum-well (MQW) distributed feedback (DFB) lasers. The analysis relies on both a very precise bi-dimensional (2D) finite-difference analysis on the quantum-well scale and on a transfer matrix analysis of the whole DFB laser cavity above threshold, that is in presence of stimulated emission. The analysis also includes to some approximation, the optical standing wave effect for both the in-phase apd the anti-phase configurations and takes into account the phase shift between the DFB grating and the optical field
