摘要： Even if there is a temperature variation, a positional discrepancy at a colliding surface of an active surface of a semiconductor laser and an optical waveguide is suppressed, resulting in realization of a semiconductor light emitting element coupled with optical fiber of stable operation. In order to realize the above object, a semiconductor light emitting element coupled with optical fiber comprises a substrate, an optical waveguide disposed on the substrate and including a core and a cladding layer covering the core, a semiconductor light emitting element disposed on the substrate and comprising an output end-surface facing one end of the core of the optical waveguide, and an optical fiber comprising a core an end of which faces the other end of the core of the optical waveguide, wherein the cladding layer sandwiches both surfaces of the semiconductor light emitting element.
