Understanding and controlling the interaction between light and matter is essential for the development of optical science and technology. We are conducting experimental research in this field and exploring new device operating principles that overcome current limitations.

Our research targets include optical-lattice clock network, EOM-based optical frequency comb, attosecond spectroscopy, spintronics, rare-earth ion-based photonic devices, and VLS-grown semiconductor nanowires. These studies are based on key experimental techniques we have developed: extreme laser control in the time and frequency domain, spectroscopy with precise time, spatial, and spin resolutions, crystal growth of high-quality materials, and fabrication of nanostructures.
