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.
