ABSTRACT:
In a optical transmission device in which a surface-emitting laser and an optical fiber are coupled, a light emitting portion of the surface-emitting laser and an input end of the optical fiber are positioned with high precision. An optical-fiber supporting member is provided with an optical-fiber through hole in which an end portion of an optical fiber is inserted, and a photodiode. The through hole and the photodiode are arranged corresponding to the arrangement of two light emitting portions of a surface-emitting laser so that a center of the circular section of the through hole and the optical axis of the optical-transmission light emitting portion are off set by a predetermined amount when a center point of the photodiode and the optical axis of the reference-light emitting portion are aligned. The surface-emitting laser and the optical-fiber supporting member are coupled with the center point of the photodiode and the optical axis of the reference-light emitting portion aligned with each other.
