Optical Path rotating device, A Semiconductor Laser Apparatus include Above Optical Path rotating device And Above Optical Path rotating device Making Method

摘要

An optical path rotating device, a semiconductor laser apparatus including the same, and a method for manufacturing the same are provided to enhance optical efficiency and minimize the number of optical components by using a micro-machining process. A method for manufacturing an optical path rotating device(300) includes a process for forming a jig including a plurality of grooves having at least one inclined side arranged in one direction. The method further includes a process for positioning one side of a dove prism on the inclined side. The method further includes a process for depositing a mask layer on a substrate having a predetermined gradient to an upper surface, a process for removing a part of the mask layer, a process for forming the inclined side, and a process for positioning one side of the dove prism on the inclined side.
