Optical waveguide detection element, video laser module, and xr glasses

Abstract

A method for manufacturing a video laser module including: a substrate provided with an optical waveguide; and a subcarrier with a laser light source mounted thereon, the method including: while supplying an electric current to the laser light source via an electrode provided in the subcarrier and oscillating a laser from the laser light source, approaching the subcarrier to an input port of the optical waveguide provided in the substrate; detecting a light intensity at an output port of the optical waveguide; adjusting a position of the subcarrier so that the light intensity is maximized; and metal-bonding the subcarrier and the substrate at a position of the subcarrier where the light intensity is maximized.
