Patent ID: 7949024

Claim:
A VCSEL array device, comprising: a grounded substrate; two or more VCSEL devices, each VCSEL device among the two or more VCSEL devices forming a first mesa on top of the grounded substrate, each first mesa forming a first side and including a lower mirror in contact with the grounded substrate, an upper mirror, an active region generating a light and positioned between the lower mirror and the upper mirror, and a first metal contact pad in electrical contact with the upper mirror; one or more short circuited devices, each short circuited device among the one or more short circuited devices forming a second mesa on top of the grounded substrate, each second mesa forming a second side and including a second metal contact pad electrically connected to grounded substrate; a plurality of metal heat sink structures deposited over each VCSEL device and each short circuited device, a first set of heat sink structures among the plurality of metal heat sink structures deposited over each VCSEL device to increase a height of each first mesa, the first set of heat sink structures electrically connected to the first metal contact pad and electrically isolated from the grounded substrate, a second set of heat sink structures among the plurality of metal heat sink structures deposited over each short circuited device and electrically connected to the second metal contact pad and electrically isolated from the first set of heat sink structures; and a heat-spreading substrate bonded to the first set of heat sink structures and the second set of heat sink structures.
