Abstract
The laser module comprises a plurality of subcarriers 20, a plurality of laser elements 30 installed on the respective main surfaces of the plurality of subcarriers 20, and an optical waveguide substrate 40 having an optical waveguide layer 50 on its main surface, the optical waveguide layer 50 having an optical waveguide 51 for guiding the laser light respectively emitted from the plurality of laser elements 30. The emission surface 50C of the optical waveguide layer 50 is inclined obliquely with respect to a plane perpendicular to the extension direction of the optical waveguide 51 at the emission surface 50C.
