We have developed a novel integration platform that conveniently merges InP and GaAs devices with SiPh in a backend processing step. Light is coupled between layers using grating couplers and total internal reflection (TIR) turning mirrors. This integration platform enables laser integration for silicon photonics and multi-chip photonic interposers. An important feature is superior heat dissipation that yields a 3X improvement in thermal impedance compared to other approaches. In addition to being featured in the OSA Optics and Photonics News magazine, this work was twice selected as a finalist for the Tingye Li Innovation Prize and was recognized with a best paper award at the 2017 Asia Communications and Photonics Conference.
