Abstract
Embodiments of a system to maintain an even temperature distribution across a laser detector are generally described herein. In some embodiments, the system includes a multi-layer printed circuit board (PCB) assembly that includes a first layer comprising a thermally-conductive ring provided circumferentially around a thermally-conductive detector region for mounting the laser detector, a second layer comprising a plurality of resistive elements aligned with the thermally-conductive detector region to generate heat, and a fourth layer comprising a thermally-conductive heat-distribution region aligned with the thermally-conductive detector region. A plurality of thermally-conductive vias is provided to couple the thermally-conductive ring of the first layer to the thermally-conductive heat-distribution region of the fourth layer. The thermally-conductive vias transfer heat between the thermally-conductive heat-distribution region and the thermally-conductive ring to provide an even distribution of heat across the laser detector.
