Patent ID: 8654811

Claim:
A Vertical Cavity Surface Emitting Laser (VCSEL) array, comprising: a first array of laser diodes; a second array of laser diodes, wherein the first and second array of laser diodes are arranged between a first mirror layer and a second mirror layer, and wherein the VCSEL array is configured to transmit through the first mirror layer, each laser diode having an anode and a cathode; and a heatsink, thermally coupled to the second mirror layer through a first metal plate and a second metal plate, wherein the anodes for the first array of laser diodes couple in parallel to the first metal plate, and wherein the cathodes for the first array of laser diodes couple in parallel to the second metal plate through an electrical path extending through a first via formed through the second mirror layer and wherein the anodes for the second array of laser diodes couple in parallel to the second metal plate to connect the first and second array of laser diodes in series.
