Ge is now gathering many attentions for integrated photonics due to its many useful optical properties. To realize a high-quality Ge thin film on Si platform, wafer bonding is promising. Recently, we have achieved high-quality Ge-on-Insulator (GeOI) wafer by wafer bonding which enables strong optical confinement for compact photonic integration. In this work, we present a proof-of-concept of a Ge/a-Si hybrid platform based on the bonded GeOI wafer.
