Abstract

A cladding mode light removal structure includes: an input-side exposure portion where a covering is removed from an end of an input-side optical fiber to expose a cladding of the input-side optical fiber; an output-side exposure portion where a covering is removed from an end of an output-side optical fiber to expose an output-side cladding of the output-side optical fiber; a fusion splice portion at which the input-side exposure portion and the output-side exposure portion are connected by fusion splice; a fiber housing portion having an accommodation space that receives the input-side exposure portion, the output-side exposure portion, and the fusion splice portion; a high refractive index resin having a refractive index equal to or higher than that of the cladding exposed at the input-side exposure portion; and a low refractive index portion of a medium.
