Abstract:
1. An optical fiber array with lenses comprising: a base plate having a first end surface and a second end surface opposite to the first end surface, the base plate having a plurality of openings arranged on the first end surface and a plurality of through-holes each opened from each of the openings to the second end surface, the through-holes each having an opening on the second end surface with a diameter smaller than that of the opening on the first end surface and a tapered inside wall whose diameter gradually decreases from the opening on the first end surface to an end of the tapered inside wall, a plurality of optical fibers each having a tip surface that is inserted into each of the through-holes in the base plate toward the opening on the second end surface through the opening on the first end surface and secured in each of the through-holes, the optical fibers each extending to the exterior of the base plate through the opening on the first end surface, and a plurality of collimator lenses each installed on each of the openings of the through-holes on the second end surface of the base plate to face the tip surface of each of the optical fibers, wherein the tapered inside wall is tapered at an angle of 1 to 10 degrees with a center axis of the through-hole.
