Abstract
A VCSEL structure having thermal management. The structure may be designed for conveyance of heat from the active layer primarily through one of the mirrors to a material that removes heat externally away from the structure. Thermal management may involve various configurations of heat removal for various VCSEL structures. The structures may be designed to effect such respective configurations for heat removal.
