OPTICAL FIBER TRANSFER LINK AND LIGHT COLLECTING DEVICE USING SAME

摘要

The present invention relates to an optical fiber transfer link having good light receiving efficiency, and a light collecting device. The optical fiber transfer link is provided with: a compound parabolic concentrator having a first end portion and a second end portion that are disposed to face one another on a single central axis passing through a body of the concentrator; and a single optical fiber having one end connected to the second end portion. The body of the compound parabolic concentrator is configured of a plurality of paraboloids, and the cross-sectional area of the first end portion is preferably formed to be greater than the cross-sectional area of the second end portion. The light collecting device is characterized by being configured of a plurality of the optical fiber transfer link of the above-described structure arranged in an array configuration.
