Abstract:
An amplification optical fiber according to the present invention includes: a core doped with an active element, through which multi-mode light propagates; an inner cladding that surrounds the core and has a refractive index lower than that of the core; and an outer cladding that surrounds the inner cladding and has a refractive index lower than that of the inner cladding. The inner cladding has a polygonal outline in a cross section perpendicular to the longitudinal direction, and the inner cladding has a permanent twist applied by turning around the central axis of the core.

Claim (Index 2):
The amplification optical fiber according to  claim 1 , wherein the permanent twist has at least three but less than 30 turns per a length of one meter in a direction parallel to the longitudinal direction.
