Dynamically Manipulating Beam with Metallic Nano-Optic Lens Containing Liquid Crystal

Abstract:

A set of metallic nano-optic lens with liquid crystal material embedded in the slits is proposed as a new idea of dynamically manipulating beam. Three kinds of metallic nano-optic lens can achieve the functions of beam deflecting, beam splitting and beam focusing respectively. The deflection angle, splitting angle and focus length can be controlled by external electrical field easily. The three phenomena are based on the principal that changing the external electrical field can control the phase of the waveguide mode in the slits.
