Abstract
A method for manufacturing an optical member includes providing a silicon substrate having a first main surface of a {110} plane, forming a mask pattern having an opening extending in a <100> direction on the first main surface of the silicon substrate, and forming a sloped surface of a {100} plane in the silicon substrate by wet etching the silicon substrate from a first main surface side using the mask pattern as a mask. A method for manufacturing a semiconductor laser device includes fixing the optical member formed by the method for manufacturing the optical member and a semiconductor laser element to a mounting board so that laser light emitted from the semiconductor laser element is irradiated to a reflective film of the optical member.
