Hybrid Photonics Research Team

Group Outline and Primary Goal

The hybrid photonics research team is conducting research and development aiming to build a framework for new hybrid photonics technology to enable further development of existing technology by integrating dissimilar materials and different technologies on a silicon photonics platform. We are engaged in a wide range of research activities from fundamentals to applications including dissimilar materials integration devices in which different types of materials such as compound semiconductors, Ge, etc. are integrated on a silicon photonics platform, combined silicon photonics/photonic crystal devices in which photonic crystal resonators and optical waveguides are integrated, fiber connection devices (elephant couplers) applying unique 90 degree bends in a direction perpendicular to a silicon waveguide, optical transmission devices that utilize these base technologies, optical arithmetic circuits, and LiDAR.
