Conductive heat spreader and heat sink assembly for optical devices
Abstract
Matching of coefficient of thermal expansion for heat spreaders and carrier die can facilitate optoelectronic die alignment. In one example, an apparatus comprises a carrier die comprising a first coefficient of thermal expansion, two or more optoelectronic die disposed on the carrier die, and a spreader. The spreader can comprise a second material coefficient of thermal expansion matched to the first coefficient of thermal expansion. Additionally, a thermal interface material is disposed between the spreader and the one or more optoelectronic die.
