title: Optical vortex converter with helical-periodically poled ferroelectric crystal.
abstract: A kind of optical vortex converter is proposed in helical-periodically poled ferroelectric crystal based on transverse electro-optics effect. It can be used to generate optical vortex from non-vortex beam and transform the topological charge of optical vortex. An optical vortex adder or substrator is proposed under the control of electric filed. This device will find its applications in high dimensional communication system for signal processing and optical manipulation in micro and mesoscopic scale.
