Paper Abstract

In diffractive optics macrostructured surface relief profiles or index-modulated media are employed to modulate electromagnetic fields in such a manner that a given optical function is achieved [1,2]. Diffractive elements range from linear gratings and microlenses to complicated structures that can shape or split a laser beam in a rather arbitrary manner, or display scenes or patterns that need not exist in the real world. In a sense diffractive optics can be understood as an extension of classical optics, in which macrostructured surface profiles of graded-index media are employed. In recent years both the design methods and the fabrication techniques have developed rapidly, and a large number of new applications have emerged. As a result diffractive optics has already become a mature technology, with considerable technological and commercial impact, in several of its application areas.
