Our Researches

Research fields in Future Semiconductor Nanophotonics Laboratory include ‘Future Semiconducting Materials’, ‘Next-generation Photonic Information Devices’, and ‘Light-Matter Interactions’. We explore new science and technologies in emerging semiconducting materials by tailoring the light-matter interactions. To this end, we pursue our studies to understand optical physics in such nanophotonic materials and to design future information devices.
