Abstract
A multi-core fiber for communication includes transmission paths that each include a single core or multiple cores mode-coupled to each other and a common cladding that surrounds an outer circumferential surface of the single core of each of the transmission paths or each of the multiple cores of each of the transmission paths. A first transmission path of the transmission paths closest to a center of the common cladding propagates light in a higher-order mode than a second transmission path of the transmission paths farthest from the center.

A multi-core fiber for communication comprising:
- transmission paths that each include a single core or multiple cores mode-coupled to each other;
- and
- a common cladding that surrounds an outer circumferential surface of the single core of each of the transmission paths or each of the multiple cores of each of the transmission paths, wherein
- a first transmission path of the transmission paths closest to a center of the common cladding propagates light in a higher-order mode than a second transmission path of the transmission paths farthest from the center.
