Paper Abstract

A new approximate analytical approach is developed and applied to investigate thermal properties of top-surface-emitting vertical- cavity diode lasers (VCSELs) mounted substrate-down. Multilayer structure of distributed-Bragg reflectors is taken into account by considering anisotropic thermal conductivity. Design conditions for minimal thermal resistance in short- and long- wavelength systems are specified for devices with various active- region diameters. Our results indicate that difficulties with obtaining the cw operation of long-wavelength VCSELs are primarily associated with intrinsic properties rather than with their thermal resistance.
