Abstract

Abstract

Recent worldwide effort has yielded prototype dynamic metasurfaces, driven mainly by component-level innovation. We describe here a design approach linking component and array-level design that can achieve near-ideal array performance for functions including beam steering and reconfigurable lensing even with highly non-ideal individual devices.

Abstract

Abstract

We report on the achievement of superior quality hexagonal boron nitride and aluminum nitride using ultrahigh temperature molecular beam epitaxy. We demonstrate high efficiency deep ultraviolet LEDs and low threshold laser diodes. Moreover, ultrahigh Q microring resonators using aluminum nitride on sapphire are also achieved.

Abstract

Abstract

In this talk, I will present a multilayer all-dielectric metasurface architecture with the goal of increasing the design landscape of metaoptics. Using this architecture we demonstrate independent control over any two properties; amplitude, phase, and polarization.
