1. A method comprising:
creating a grating stage by:
preparing a first side of at least one of two substrates to include photo-alignment properties;
placing a liquid crystal layer between the two substrates adjacent to the first side; and
coupling a transparent electrode to a second side of the at least one of the two substrates, wherein the second side opposes the first side;
arranging a plurality of grating stages in a spatial light modulator;
selectively biasing a grating stage of the plurality with a grating period such that optical energy from traversing light in plus and minus first orders is deflected and optical energy from traversing light in a zero order is allowed to pass through the grating stage with a polarization state of the traversing light maintained.
