Dynamic control of visible light with dielectric nanoantennas: towards next-gen spatial light modulators (Conference Presentation)

Paper Abstract

In this talk, we will present our recent results towards dynamic control of individual dielectric nanoantennas. The goal is to develop a platform enabling the new generation of Spatial Light Modulators with sub-wavelength pixel size for visible light applications. In particular, we will present a transmissive device based on resonant titanium dioxide nanoantennas embedded in liquid crystals, with a pixel size of only one micrometer and operating at a wavelength og 660 nm. We demonstrate full re-configurability of the device via dynamic beam steering, with as large as 40% diffraction efficiency with respect to incident light and more than 20 degrees field of view. We will also show future prospects to further increase this efficiency and further miniaturize the pixel size.
