Multi-functional Metafilms for Augmented Reality
Abstract
Many vision applications require capabilities that surpass what humans can see with the nakedeye. For example, seeing in darkness or foggy conditions or spotting of objectsemitting/scattering light with specific spectral or polarization properties can require enhancedvision. In many cases, it is also desirable to quantify and store information about a scene. For thisreason, enhanced vision devices and specialty cameras are essential tools in defense applications.Unfortunately, these devices tend to be very bulky and do not meet the size, weight, and powerrequirements that are desirable for wearables. In the proposed program, the Brongersma groupaims to realize multifunctional metafilms on transparent silica substrates to both enhance opticalimages and perform advanced filtering and photodetection functions. The metafilms will beconstructed from resonant semiconductor (mostly Si) nanostructures. The metasurfaces will beultrathin and could thus be applied to regular eyeglasses. The realization of this exciting vision requires the elucidation of the fundamental optical physics that underpins the operation of thenanostructured metafilms and ways to fabricate them over large area (cm2).
