COUPLING OPTICAL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a coupling optical system capable of surely coupling a core and an optical circuit in a one to one relationship when coupling a multi-core fiber and an optical circuit array.

SOLUTION: The coupling optical system couples the optical circuit array in which emission ends or incident ends of the optical circuit are aligned one dimensionally and the multi-core fiber in which a plurality of cores are two dimensionally arrayed. The coupling optical system includes an optical path conversion circuit for optically coupling the one dimensionally aligned emission ends or incident ends of the optical circuits to the two dimensionally arrayed cores.
