Paper Abstract

We introduce a method for designing high-efficiency paraxial-domain diffractive elements working over a broad frequency range. The design method is based on the theory of dielectric polarization gratings, in which the local state of polarization is controlled by means of form-birefringent diffractive structures. We show that any scalar transmission function can be easily converted to a corresponding broadband design.
