Abstract
A monolithic polarizing diffractive structure includes a system having at least two parallel continuous planar surfaces, a diffractive pattern on one of the at least two parallel continuous surfaces, the diffractive pattern including at least two diffractive elements integral with the one of the at least two continuous surfaces, the at least two diffractive elements defining a monolithic diffractive pattern, and a polarizing pattern on one of the at least two parallel continuous surfaces. The polarizing pattern includes at least two polarizing elements, each polarizing element corresponding to a respective diffractive element, the at least two polarizing elements outputting polarizations rotated with respect to one another, the at least two polarizing elements defining a monolithic polarizing pattern.
