The concept of polarization freedom is employed to design diffraction gratings that are
capable of transforming an electromagnetic plane wave into two or three diffraction orders …

A binary diffractive optical element, acting as a polarizing beam splitter, is proposed and
analyzed. It behaves like a transmissive blazed grating, working on the first or the second …

Diffractive elements with polarization multiplexing for the visible spectral region are
demonstrated. The polarization-multiplexing property of the element is based on the …

We extend the rigorous eigenmode theory of binary surface-relief gratings to accommodate
three-dimensional-modulation profiles, to formulate a synthesis problem for doubly periodic …

Publisher Summary This chapter discusses the electromagnetic approach for the diffractive
optics. The chapter focuses on the domain of diffractive optics in which rigorous …

Resonance-domain diffractive optics covers the region where the characteristic feature sizes
in the surface-relief modulation structure of the diffractive optical element are comparable to …

We report here on the theoretical performance of blazed binary diffractive elements
composed of pillars carefully arranged on a two-dimensional grid whose period is smaller …

An upper bound of the diffraction efficiency of diffractive elements that only influence the
phase of the illumination wave is derived. The derivation only utilizes the specification of the …

We show how suitable combinations of cascaded diffractive optical elements (DOEs) can
form a combined “moiré DOE” of adjustable refractive power and high diffraction efficiency …

It is shown from numerical results deduced from a rigorous theory of diffraction that
diffraction gratings made with two-dimensional dielectric photonic crystals may present …
