Control of Light-Matter Interactions using Photonic NanostructuresResearch

The optical response of a material depends on the surrounding electromagnetic environment. By artificially controlling the radiation field using photonic nanostructures, it becomes possible to manipulate the optical response of materials. This approach holds promise for improving the efficiency of photonic devices, enabling unconventional optical responses, and realizing novel device functionalities. We are conducting research on emission control and device applications using photonic crystals and photonic crystal nanocavities that incorporate emitters such as quantum dots.
Our work includes the exploration of cavity quantum electrodynamics (QED) and the development of quantum optical components. In addition, we are investigating both the fundamental physics and applications of optical angular momentum control and spin–orbit interactions of light.
