<p>[PROBLEMS] The first problem is to provide an optical fuse with small insertion loss. The second problem is to provide an optical fuse so devised that the optical coupling is canceled after an irreversible charge is induced. [MEANS FOR SOLVING PROBLEMS] An optical fuse has a structure in which the light exit end of an optical waveguide is coupled to the light entrance end of another optical waveguide with a medium interposed between the optical waveguides, wherein the medium is transparent to light propagated through the constituent material, and a light-absorber absorbing the light is in contact with the side surface of the medium and is so disposed that a part of the light entering the medium from the light exit end reaches the light-absorber. Also disclosed is a component for fabricating an optical fuse, so devised that two supports adapted to support an optical fiber and having a through hole are connected through a beam. The component is characterized in that the lines passing the centers of the through holes are aligned with each other, and a section where an optical fiber is out of contact with the beam is present when one optical fiber is passed through both through holes.</p> |
