Abstract

Diffractive optical elements are being used in increasing numbers of applications such as beam shaping, optical interconnects and filtering. Their main advantages over traditional refractive optical elements are their reduced size and weight and the possibility of being mass fabricated. In order to reduce the design complexity and increase the performance, a novel, full complex-amplitude modulation diffractive optical element was designed, which allows full control over both phase and amplitude modulation of whatever optical wave front. In this element the wavefront phase modulation is controlled by the variations in the thickness of an optical film and the magnitude modulation is controlled by variations in the area of the apertures in a reflective layer deposited over this film. The use of a reflective layer in this new diffractive element avoids the risk of laser-induced damage when a powerful laser is used with the element since no light absorption is involved in the process.
