ABSTRACT:
A semiconductor laser module includes: a semiconductor substrate; a plurality of surface emitting lasers provided on a primary plane of the semiconductor substrate; a plurality of guiding holes provided on a secondary plane of the semiconductor substrate, the secondary plane being opposite to the primary plane; and an optical fiber tape including a plurality of optical fibers and a covering material which fixes the plurality of optical fibers in parallel with each other, one tip of the optical fiber tape being adjoined to the secondary plane of the semiconductor substrate. A pitch of the respective surface emitting lasers is equal to an interval of a center of the respective optical fibers. The respective guiding holes are aligned with the respective surface emitting lasers so that a center of a light beam emitted from each of the surface emitting lasers and a center of each of the guiding holes are at approximately the same position on the secondary plane of the semiconductor substrate. A diameter of each of the guiding holes is substantially equal to an outer diameter of each of the optical fibers. And a portion of the respective optical fibers at tips thereof is exposed from the covering material and inserted into the respective guiding holes.
