Abstract

A method for designing high-efficiency paraxial domain diffractive elements working over a broad wavelenght is introduced. These elements are based on polarization gratings that manipulate spacially the local state of polarization using form bifringent subwavelenth diffractive structures. Any scaler transmission function can realized simulataneosly for a wide band of wavelenths using such elements. In some cases it is also possible to design beam splitters that exceed the scalar paraxial-domain upper bounds of diffraction efficienty over a broad wavelength band.
