"Flat Optics"

 

In this talk, I will describe our demonstration of miniature visible silicon nitride pure phase modulators based on micro-resonators. These devices offer a one-order-of-magnitude reduction in device footprint and power consumption compared to waveguide-based phase shifters. I will also describe the effort of my research lab in investigating structural dispersion engineering of meta-atoms and creating passive metasurface-based flat optical devices using the meta-atoms. These include broadband achromatic flat lenses for full-color imaging and phase-amplitude metasurface holograms for creating defect-free holographic objects.
