Abstract:
The present embodiment relates to a CMCF including a structure to achieve more efficient reduction in transmission loss by suppressing decrease in concentration of alkali metal due to diffusion of alkali metal. In the CMCF including a plurality of cores, a power coupling coefficient h between adjacent cores is set to 1×10 −3 /m or more, to maintain an optical coupling state between the adjacent cores. In addition, alkali metal contributing to reduction in transmission loss is added to each of the cores such that a stress maximum value σ_ max  between adjacent cores has a negative value.

Claim (Index 9):
The coupled multi-core optical fiber according to  claim 1 , wherein\n concentration of the alkali metal in a surface of the cladding is 1 atom ppm or less.
