Abstract
An end faceof an optical fiberand an end faceof an optical fiberare arranged so as to have a predetermined interval and to oppose each other in a V-grooveof a base. A solutionincluding particles used as a material of the photonic crystal is dropped into a space sectionwhich is formed by the end face, the end face, and the V-groove. Accordingly, by growing the photonic crystal from each of the end faceand the end face, the optical control section including the photonic crystalis formed on each of the end faceand the end face
