WD2.1 - DYNAMIC TWO-DIMENSIONAL OPTICAL METASURFACES: CONNECTING NANOPHOTONIC AND ARRAY ARCHITECTURE DESIGN
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.WD2.2 - TUNABLE OPTICS BASED ON PHASE-TRANSITION MATERIALS
Abstract
Abstract
I will describe our latest work on tunable optical materials and adjacent topics, including the use of the phase-transition of vanadium dioxide to enable tunable devices and integration into frequency selective surfaces and metasurfaces, and new optical materials with giant anisotropy.
WD2.3 - ULTRAHIGH TEMPERATURE MOLECULAR BEAM EPITAXY OF BORON NITRIDE AND ALUMINUM NITRIDE FOR ULTRAVIOLET PHOTONIC AND EXCITONIC 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.
WD2.4 - MULTIFUNCTIONAL METAOPTICS BASED ON MULTILAYER METASURFACES
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.
