Optical module having optical assembly precisely aligned with optical fiber

摘要

An optical module with an optical subassembly precisely aligned with an optical fiber is disclosed even when the optical axis of the optical subassembly and that of the optical fiber are perpendicular to each other. The optical module has an auxiliary with a knob and a flange each having a concentric circular periphery. The knob is held by chuck of the welding apparatus, while, the optical subassembly is fixed to the flange. Even when the optical subassembly is slid on the flange to align optically with the optical fiber, the positions of the laser beams for welding are kept on the periphery of the flange.
