Paper Abstract

Continuous surface-relief phase gratings for two-dimensional (2-D) array generation have been designed and fabricated by laser-beam writing lithography. Separable and non-separable solutions for the design of 2-D fan-out elements are compared. A 9 X 9 fan-out element has been fabricated in photoresist by laser-beam writing. A diffraction efficiency of 94% and an uniformity better than +/- 8% over the whole array were achieved.
