Device for aligning optical source and optical fiber in optical source module

摘要

Disclosed is a device for aligning an optical source and an optical fiber in an optical source module. The optical source module has a substrate, an optical source mounted on the substrate, an optical fiber for receiving lights emitted by the optical source, an optical fiber ferrule for supporting the optical fiber, and a saddle mounted on the substrate for holding the optical fiber ferrule. The saddle comprises a pair of base layers distanced apart from each other so that the optical fiber ferrule can be inserted thereto; a sub-rib member extending upwardly from internal ends of the respective base layer; a center-rib member extending in a vertical upward direction from the center of the respective sub-rib member; an arm member displaced along the longitudinal direction of the optical fiber ferrule, and having a pair of welded sections for coupling the optical fiber ferrule thereto; a tapered reinforcing member extending from the respective arm member; and, a loop member having a bent shape coupled to both ends of the reinforcing sections.
