Miniaturization of photonics devices is highly demanded for future photonic integrated circuits. We are investigating semiconductor photonic nanostructures, such as photonic crystals, as a platform enabling the advanced control of the flow of light and light-matter interactions in a wavelength scale. We are also advancing research aimed at creating innovative nanophotonic devices that are utilizing the concept of topology.
