Abstract
Tunable nanostructures and nanocavities can be used to manipulate dynamically an incoming wavefront at sub-wavelength scales. Realizing such systems is, however, challenging both from the design aspects, particularly if one looks for practical configurations with single-pixel control. In this talk, we will show how interfacing liquid crystals with different nanocavities can be used for this means. In particular, we will present configurations employing dielectric nanoantennas for dynamic beam steering with single-pixel control and extended field of view, as well as the potential of Fabry-Perot nanocavities to extend these devices to multi-chromatic (RGB) operation.
