Systems and methods to provide compact, scalable, low loss optical switches. An optical switch of this invention includes two or more directing elements, each directing element having two or more sections. Each section includes a switchable deviating element. During operation of a two element optical switch of this invention, the first section of the first element can selectively deviate in a first direction the input beam for that section. The second section of the first element can selectively deviate in a second direction the input beam for that section. The optical beams transmitted by the first element constitute the input beams for the second element. The first section of the second element can selectively deviate in a third direction, which can be the same as the first or second direction, the input beam for that section. The second section of the second element can selectively deviate in a fourth direction, which can be the same as the first or second direction, the input beam for that section. By selecting the relationship between the third direction and the first or second direction and the relationship between the fourth direction and the first or second direction, different designs are obtained.

A PDLC transmissive phase grating utilizing nematic liquid crystal materials confined in a polymer matrix. The PDLC grating operates in the Bragg regime and switches between diffracting and non-diffracting states via an applied electric field. The grating is made up of a PDLC grating film contained within a cell. The PDLC film has a spatially periodic distribution of grating planes which includes polymer-rich regions and liquid crystal-rich regions, wherein the major constituent of the polymer-rich regions is a polymer, and wherein the liquid crystal constituent concentration within the liquid crystal-rich regions is greater than the liquid crystal constituent concentration within said polymer-rich regions. The PDLC transmission phase grating is rendered substantially transparent when subjected to an electric field during the application of light that is p-polarized and incident on the grating at Bragg angle.
