Abstract
Heat dissipation from III-V based heterogeneously integrated lasers is challenging in the presence of the thermally isolating bonding layer. Herein, we explore two ways to improve heat dissipation of devices bonded with benzocyclobutene (BCB): bonding with ultra-thin BCB on a SiC substrate, and thick metal vias connecting lasers to a Si substrate, both resulted in 2× improved heat dissipation compared to devices without a conductive connection to the heat sink.
