Mitigated Temperature Gradient-Distributed Bragg Reflector

摘要

A semiconductor laser system comprising a gain region, a gain contact coupled to the gain region, and a distributed Bragg reflector (DBR) having a near side and a far side with respect to the gain region are provided. The DBR reflects a resonant frequency of light back into the gain region. The semiconductor laser system further comprises a heat conducting structure, wherein the heat-conducting structure is positioned to transfer heat in a direction from the near side to the far side of the DBR grating, and an outcoupler, positioned to outcouple the resonant frequency of light from the semiconductor laser system.
