MULTICORE/MULTIMODE FIBER COUPLING DEVICE

摘要

A device for coupling a multicore/multimode fiber that can transmit a large quantity of information. This multicore/multimode fiber coupling device has a first fiber group (11), a first light converging system (13), a first mode converter (15), a second fiber group (21), a second light converging system (23), and light converging system (33) for multicore fibers. By means of the first mode converter (15), light from the first fiber group (11) is subjected to mode conversion en masse. A space coupling system (33) for multicore fibers transmits light derived from the second fiber group (21) and light derived from the first fiber group (11) subjected to mode conversion to the multicore fibers (31).

1. A multi-core multi-mode fiber coupling device comprising:
a first group (11) of fibers; a first light converging system (13) which converges a group of outgoing light beams from the first group (11) of fibers; a first mode converter (15) which converts a mode of the group of outgoing light beams from the first group (11) of fibers, which has been converged by the first light converging system (13), into a first mode; a second group (21) of fibers; a second light converging system (23) which converges a group of outgoing light beams from the second group (21) of fibers, and a spatial coupling system (33) for multi-core fiber which guides a group of outgoing light beams from the first mode converter (15) and a group of outgoing light beams from the second light converging system (23) into a multi-core fiber (31).
