Quantum symmetry, especially parity-time (PT) symmetry, has been widely explored in nanostructures and waveguides for developing a new generation of

A new technology that can allow for better light control without requiring large, difficult-to-integrate materials and structures has been developed

Our group developed a new type of time-variant optical metasurface with which phase modulation in both space and time is

Metamaterial-based optical cloaks have thus far used volumetric distribution of the material properties to gradually bend light and thereby obscure

Holography, a revolutionary 3D imaging technique, has been developed for storing and recovering the amplitude and phase of light scattered
