Abstract

Diffractive optics elements (DOE’s) are widely used for laser beam focusing, coupling, collimating, shaping and light beam array generation. In those applications specific functionalities of the DOE and diffraction efficiency, instead of aberrations, are the most important issues. The design of a DOE depends on the specifications of the DOE and is subjected to the fabrication constraints. Our objective is to achieve the best performance of the diffractive coupling lenses and array generation gratings under the given fabrication constraints.
