Paper Abstract

The fabrication of diffractive optics and digital optics on fused silica has been investigated in this paper. The diffractive optics has been fabricated by using the gray- scale mask technique. The gray scale mask is fabricated on the HERB glass. RIE is used to realize the pattern transfer from the photoresist to the fused silica for the diffractive optics and the etching for the digital optics. The processing parameters are discussed in detail and the influence of exposure and development of the photoresist are also addressed in this paper. These diffractive optics and digital optics were designed to collimate optical radiation.
