The phenomenon of resonant mode coupling is modeled and numerically investigated in InGaN-based multiple-quantum-well laser structures. It is shown that under resonant conditions, the internal mode coupling can lead to severe distortions of both near

A comprehensive self-consistent thermal-electrical model is described and used to investigate thermal properties of GaAs-AlGaAs etched-well double-heterostructure vertical-cavity surface-emitting lasers (VCSELs) with dielectric mirrors. Special atten

A comprehensive two-dimensional model for analysis of thermal effects in etched-well vertical-cavity surface-emitting lasers is presented. A self-consistent solution for the electrical and thermal processes is obtained numerically. Joule heating is s

It is suggested, contrary to present views, that the processes giving rise to radiation in undoped or lightly doped quantum well laser diodes can be described by using a no k -selection model. The reason is contained in the good fit of experimental g

Multiple feedback effects on the output power and spectral characteristics of an external cavity semiconductor laser with asymmetric feedback induced by misalignment of an external mirror are discussed. The external mirror tilt modifies the round-tri

A surface-emitting semiconductor laser structure with a vertical cavity, extremely short gain medium length, and enhanced gain at a specific design wavelength is described. The active region consists of a series of quantum wells spaced at one half th

The objective of this paper is to present an overview of topics related to one of the fundamental parameters for semiconductor lasers-the linewidth broadening factor α that describes the coupling between carrier-concentration-induced variations of r
