Abstract
Compared to conventional optical elements, photonic metasurfaces, consisting of arrays of antennas with subwavelength feature size, enable the manipulation of light-matter interaction in a more compact way. Using metasurfaces, the polarization, phase and amplitude of light can be well controlled by engineering the functionalities of the individual meta-atoms and their interactions. Many exotic phenomena in both linear and nonlinear optical regimes, such as wavefront engineering, optical holography, frequency conversion, have been successfully demonstrated. In this talk, I will share our latest progress on these topics. In addition, the design principle and large area nanofabrication of metasurface diffractive optical elements will be discussed.
