Abstract
An optical connection apparatus comprising a prism that extracts N×M beams of outgoing light from an optical circuit, a two-dimensional GRIN lens array of N×M GRIN lenses, a spacer, having a thickness according to the optical path length in the prism, that transmits N×M outgoing beams from the two-dimensional GRIN lens array, and a two-dimensional fiber array that causes the N×M beams to be incident on optical fibers, the ends of optical fibers being disposed at the focal point of each of the beams transmitted through the spacer.
