Abstract
A method for producing a semiconductor laser module is provided which enables simplifying the production process by eliminating the process of positioning the laser light emitting portion on the substrate, as well as enabling positioning an optical fiber on an appropriate position without aligning the optical fiber with the laser light emitting portion. A semiconductor laser module is fabricated through a process including a substrate preparation step for preparing a substrate including an active layer between cladding layers; a supporting groove portion formation step for forming a supporting groove portion to support an optical fiber on the substrate; and an electrode formation step for forming an electrode on a substrate surface of an opposing portion which faces the supporting groove portion.
