Abstract
This study presents a special -type (45°, 135°) microprism structure design for the lateral-type semiconductor laser of optical systems. This study combines front- and back-side inclined exposure technology to develop a -type microprism structure and replaces the optical prism manufactured through traditional machine processing or injection molding with a new polymer (thick-film negative photoresists) micro-optical prism structure. To obtain the optimal structural surface roughness (12–15 nm at area), the percentage of polymer material loss caused by the solvent was controlled. This roughness level meets Blu-ray specifications (, ).
