Abstract

Techniques and systems for a semiconductor laser, namely a grating-coupled surface-emitting (GCSE) comb laser, having thermal management for facilitating dissipation of heat, integrated thereon. The thermal management is structured in manner that prevents deformation or damage to the GCSE laser chips included in the semiconductor laser implementation. The disclosed thermal management elements integrated in the laser can include: heat sinks; support bars; solder joints; thermal interface material (TIM); silicon vias (TSV); and terminal conductive sheets. Support bars, for example, having the GCSE laser chip positioned between the bars and having a height that is higher than a thickness of the GCSE laser chip. Accordingly, the heat sink can be placed on top of the support bars such that heat is dissipated from the GCSE laser chip, and the heat sink is separated from directed contact with the GCSE laser chip due to the height of the support bars.
