Abstract

In accordance with an embodiment, a welding assembly is disclosed that allows for a laser assembly to be coupled into a socket of the same and held at a fixed position, e.g., by a mechanical grabber of a welding system. The mechanical grabber may then travel along one or more axis to bring the TOSA module into mechanical alignment with an opening of an associated optical subassembly housing. The welding assembly may further include an alignment member that provides one or more alignment contact surfaces configured to be brought directly into contact with a surface of the associated subassembly housing. When the one or more alignment contact surfaces are “flush” with the surface of the subassembly housing the emission face of the TOSA module is substantially parallel, and by extension, optically aligned with the opening of the associated subassembly housing.
