Abstract
The invention provides an optical module, in which a surface-emitting laser and an optical fiber are coupled, with the optical axes thereof crossed at a predetermined angle, at low cost. A supporting member supports the end of an optical fiber, in which the extending direction of a through hole and a face at the optical fiber end are orthogonal to each other. A surface-emitting laser and the supporting member are coupled by metal projections having different heights, so that a light-emitting face of the surface-emitting laser and the face of the supporting member are disposed so as to be opposed to each other at a predetermined angle. After the projections are formed on an electrode and metal patterns on the surface of the surface-emitting laser by a method based on wire bonding, the leading ends thereof are fixed to metal patterns of the supporting member by ultrasonic welding.
