Liquid Crystal Flat Optical Elements

ORAL

Abstract

Thin liquid crystal films (LCs) with well-defined molecular orientations are an exceptional platform for making flat optical devices based on the Pancharatnam-Berry phase. Here we present a new approach to designing and fabricating liquid crystal flat optical elements such as micro-lenses and beam-shapers. We show the molecular orientation patterns for shaping a light beam into desired intensity profiles can be designed using a generalized Snell’s law, and that such liquid crystal flat optical elements can be made with high throughput and high resolution by using a plasmonic-metamask-based photopatterning approach.
