Switchable Zero Order Diffraction Gratings as Light Valves.

Abstract

The goal of this project is to produce a light valve based on the cancellation of the zero order of diffraction. The light valve works by displacement of two facing gratings with respect to one another by half an operating period. The light valve is made of polyvinylidine fluoride (PVF2) a piezoelectric plastic. It is simple cheap and, in principle, mass producible into arrays to serve as a flat display or as a light modulator in optical signal processing.
