Abstract

Systems and methods are described herein for an optical beam-steering device that includes an optical transmitter and/or receiver to transmit and/or receive optical radiation from an optically reflective surface. An array of adjustable dielectric resonator elements is arranged on the surface with inter-element spacings less than an optical operating wavelength. A controller applies a pattern of voltage differentials to the adjustable dielectric resonator elements. The pattern of voltage differentials corresponds to a sub-wavelength reflection phase pattern for reflecting the optical electromagnetic radiation. One embodiment of a dielectric resonator element includes first and second dielectric members extending from the surface. The dielectric resonator elements are spaced from one another to form a gap or channel therebetween. A voltage-controlled adjustable refractive index material is disposed within the gap.
