Hybrid GaInAsP/SOI ridge waveguide Fabry–Pérot lasers with reduced thermal resistance were fabricated and measured. The lasers were formed by room-temperature surface-activated bonding of InP and silicon-on-insulator wafers. Thin SiO2 film was int

In III-V/SOI hybrid photonic devices, the mode size between III-V/SOI hybrid section and Si waveguide are very different. To obtain high coupling efficiency between them, we investigated taper length dependence of a double taper-type coupler which en

An optical mode converter between hybrid device and Si waveguide is the key component for efficient and stable operation of III–V/silicon-on-insulator (SOI) hybrid photonic integrated circuits (PICs). In this study, we introduced a double taper str
