Overview

We are interested in theoretical and experimental studies on light interaction with structured materials. In particular, we are performing intensive studies on light manipulation in two-dimensional (2D) space, enabled by both natural 2D crystals such as graphene and boron nitride, and artificial 2D metasurfaces. This understanding is essential for the control of light in reduced space dimensions, and, more importantly, for further progress of micro- and nano-optics in low-dimensional spaces.
