Abstract
A laser module that can suppress influence due to a reflected light between chips is provided. A laser moduleaccording to one embodiment of the present invention includes: a laser elementprovided on a first substrate and having a laser oscillation unit that generates a laser light and a first optical waveguide that guides the laser light; and an optical amplifierprovided on a second substrate and having a second waveguide that guides the laser light. The first optical waveguide is nonparallel relative to an end face of the first substrate and connected thereto, the second optical waveguide is nonparallel relative to an end face of the second substrate and connected thereto, and the first substrate and the second substrate are arranged such that the laser light output from the first optical waveguide is optically coupled to the second optical waveguide.
