A comprehensive model is presented to study filamentation in both conventional double heterostructure (DH) and quantum well (QW) semiconductor lasers. The spatial dynamics of broad-area (BA) semiconductor lasers is studied by numerically solving space-dependent coupled partial differential equations for the complex optical fields and the carrier density distribution. A self-consistent iteration is...
Microscopic voids in the die attachment solder layers of high power laser diodes (HPLDs) cause to degrade their overall thermal transfer performance. This paper presents the effects of voids on the thermal conductivity, leakage and threshold currents, characteristic temperature (T 0 ) and output power of a single quantum well (SQW) HPLD. These effects are modeled by means of finite difference...
