摘要： The present invention is related to a laser diode module and a fabricating method therefor, which facilitate the fabrication and enable fabrication in a short time with a low cost and high long-range reliability. With a lens formed fiber (8) and a laser diode element (LD element) (3) aligned with each other, the front side edge portion of the ferule 4 near the LD element 3 are fixedly sandwiched on the both sides thereof by means of a ferule supporting part (6) to form a sandwiched portion (9). By a fulcrum at sandwiched portion (9), the rear side edge portion of the ferule (4) is displaced to re-align the lens formed fiber (8) with the LD element (3).

摘要： A laser diode module is provided which is capable of suppressing reduction in the efficiency of laser beam coupling with an optical fiber even in the case where a warp is caused in the mounting surface of a thermo electrical cooler on which a laser diode chip is mounted. A laser diode module has a heat sink and optical coupling portion mounted directly or indirectly on a mounting surface of a thermo electrical cooler. A laser diode chip and the optical coupling portion are located on the same side of the mounting surface along the emitting direction of a laser beam emitted from the laser diode chip, with respect to a first center line (Lcpp) intersecting perpendicularly with a tangential plane tangent to the mounting surface of the thermo electrical cooler at the center thereof and/or a second center line passing through the center of the mounting surface of the thermo electrical cooler and perpendicular to both the first center line and an axis representative of the emitting direction of the laser beam.

摘要： The present invention discloses an optical fiber capable of providing optical connection to a semiconductor laser diode (LD) as a light emitting element at high optical coupling efficiency. An optical fiber (5) for optical coupling efficiency improvement is-coupled, by a fusion joint technique, to an end portion of an optical fiber (2) which is optically connected to a semiconductor LD (3). The optical fiber (5) for optical coupling efficiency improvement has a circular mode field w and the semiconductor LD (3) has an elliptical mode field, wherein the diameter W1 of the fiber (5) is nearly identical to that of the latter field of the semiconductor LD (3) extending in the ellipse's major axis direction. Further, an end portion of the optical fiber 5 for optical coupling efficiency improvement on the side of the semiconductor LD (3) is formed into an approximately wedge-like shape and its endmost portion is formed into a lens.
