A method of achieving improved radial alignment in an optical package utilizing laser welding techniques

摘要

A laser-welding technique for precisely locking the XYZ alignment of the fiber in a laser package is described. Laser welding the fiber with 0.5- mu m precision has been achieved with a high yield. The laser-welded joints' mechanical stability is satisfactory. Piece part geometries, the sequence of tasks needed to secure the fiber within the laser package, and the long-term stability of the welded joints are considered.
