    Abstract: PROBLEM TO BE SOLVED: To provide a coupled multicore fiber facilitating a mode separation in a mode multiplex transmission while retaining the coupling of cores.SOLUTION: A coupled multicore fiber 10 includes a plurality of cores 11 and a clad 12 surrounding the plurality of cores 11. The plurality of cores 11 are arranged such that periphery surfaces of the adjacent cores 11 come into contact with each other. Each of the cores 11 is configured to have a refractive index higher than that of the clad 12 and includes: an outer region 16 having a predetermined thickness from the periphery surface; and an inner region 15 configured to have a higher refractive index than that of the outer region 16 and surrounded by the outer region 16.
