Large-scale, Compound Metaoptics For Complete Wavefront Control
Abstract
Year 1: Initial demonstration of phase and amplitude control with a metaoptic at NIR wavelengths1. Fabrication (e-beam lithography), assembly and measurement of a metaoptic at NIR wavelengths that controls the amplitude and phase of an aperture along one dimension for a single polarization.2. Initial development of the large-scale, holographic microsphere lithography technique.Year 2: Pushing the limits on amplitude, phase and polarization control1. Fabrication, assembly and measurement of a metaoptic that achieves such control at NIR wavelengths.2. Continued development of the large-scale holographic microsphere projection lithography technique, and fabrication of metaoptic prototypes using the technique.3. Development of stackable GaP-based metasurfaces for the fabrication of metaoptics at visible wavelengths.Year 3: Complex-valued holograms, and multi-input multi-output metaoptics1. Fabrication (using large-scale holographic microsphere projection lithography), assembly and measurement of a compound metaoptic (silicon based) that recreates a complex-valued three-dimensional hologram at NIR wavelengths. These metasurfaces will be fabricated over an area of ~1 cm x 1 cm.2. Fabrication (using EBL), assembly and measurement of a compound metaoptic (GaP based) that recreates a complex-valued three-dimensional hologram at visible wavelengths. These metasurfaces will be fabricated over an area of ~2 mm x 2mm at the Center for Nanophase Materials Science at Oak Ridge National Laboratory.3. Demonstration of a proof-of-concept experimental prototype.
