Abstract
The multi-core optical fiber comprises cores embedded in common cladding, with each core containing a dopant. A "peculiar" one of the cores has a central zone that is not doped by the dopant, the other cores all being completely doped by the dopant, thereby enabling the peculiar core to be used as a local reference point in order to locate the cores of the optical fiber individually.
