Achromatic and wide field-of-view metalens design
… and have limited focusing quality. Here a novel metalens design is presented which shows extraordinary achromatic and WFOV focusing quality simultaneously. The metalens is composed of all-dielectric meta-atoms selected from a large meta-atoms library with diverse dispersion behavior. The metalens …

Multi-functional flat optics for imaging and sensing
… the design concept of wide field-of-view metalens for imaging applications. We proposed the analytical solution to obtain the optimum phase profile of the single layer wide field-of-view metalens, which show diffraction-limited imaging performance with near-180° field-of-view. We further …

Metasurfaces and Their Applications in Photonic Devices
… show its enhanced performance when cascaded with metalens and meta-prism. Additionally, we design nonlocal metasurfaces capable of shaping spatial properties of light within a narrow spectral range, and demonstrate their applications in beam steering, focusing, and chiral dichroism. We anticipate …

Advanced light manipulation and waveguiding in plasmonic nanostructured optical fibers.
… fibers, leading to the development of in-fiber metalens. The third project involves the integration of plasmonic nano-circuits on the facet of polarization-maintaining photonic crystal fiber (PM-PCF) and panda-shaped PM-optical fibers. A Yagi-Uda antenna-coupled low loss plasmonic slot waveguide …
