ABSTRACT:
An optical fiber array with lenses connected with a plurality of optical fibers is disclosed, enabling to be manufactured to meet the optical fiber end intervals to the terminal intervals of an optical device to be connected and having an improved efficiency in connection operation. The optical fiber array comprises a base plate having a first end surface and a second end surface opposite to the first end surface, a plurality of optical fibers having a tip surface inserted and secured in each of the holes opened on the base plate, and a plurality of collimator lenses installed on the second end surface facing the tip surfaces of the optical fiber. Each hole has a tapered inside wall having a diameter gradually decreasing from an opening on the first end surface of the base plate toward the second end surface and a parallel inside wall continuing from the tapered inside wall end. In the hole, a refraction index matching agent is preferably filled in between the tip surface of the optical fiber and the collimator lens. The optical fiber array is designed so as to match the optical axis pitches of the optical fibers and collimator lenses to the terminal pitches of the optical device to be connected.
