載の光フアイバコネクタ。[Scope of Claim for Utility Model Registration] (1) In an optical fiber connector that is attached to the end of an optical fiber and has an air layer as a cladding so that the cladding mode can also be propagated, the area near the input end of the optical fiber in the light-receiving connector An optical fiber connector characterized in that a light-receiving means for cladding mode light is disposed in the cladding mode light, and a resin having a higher refractive index than the cladding is interposed between the light-receiving surface of the light-receiving means and the cladding of the optical fiber. (2) an optical fiber for cladding mode detection, in which the light receiving means has a reflective surface with a metal vapor-deposited film formed on the tip thereof at an angle in order to reflect the cladding mode light received from the light receiving surface and take it into the optical fiber;
The optical fiber connector according to claim 1, which is a registered utility model, characterized in that it is comprised of a fluorescent plate that emits visible light by the light emitted from the optical fiber for detecting the cladding mode. (3) The optical fiber connector according to claim 1, wherein the light receiving means is comprised of a photoelectric conversion element. (4) The optical fiber connector according to claim 1, wherein the light receiving means is composed of a thermocouple.
