Paper Abstract

It has recently become apparent that a comprehensive quantum well (QW) laser design strategy must address the complicated distribution of carriers both in real and in momentum space throughout the laser structure. Therefore, in addition to appropriate material systems, optimized QW width, and proper light guiding structures, one must carefully optimize the width and the doping of the separate confinement heterostructure (SCH), and tailor the cladding layer/SCH and the SCH/QW bandgap discontinuities. In this talk, we describe new simulation techniques to address these issues and illustrate the importance of optimizing bandgap discontinuities through a study of hot phonon effects on laser performance.
