Abstract :
The paper utilizes finite element analysis to systematically investigate heat flux and thermal resistance of lasers with different combinations of a bottom DBR (InGaAsP/InP, AlAs/GaAs, or SiO2/Si) and a top DBR. The latter consists of pairs of a low index material (SiO2, Al2O3, CaF2 , Si3N4, MgO, or BeO) and a high index material (Si, TiO2, ZnSe, or SiC). 1.55 μm VCSELs with polyimide or InP insulating regrowth in top-up or top-down mounting are considered
