A fiber optic connector and method for connecting composite materials within which optical fibers are imbedded. The fiber optic connector includes a capillary tube for receiving optical fibers at opposing ends. The method involves inserting a first optical fiber into the capillary tube and imbedding the unit in the end of a softened composite material. The capillary tube is injected with a coupling medium which subsequently solidifies. The composite material is machined to a desired configuration. An external optical fiber is then inserted into the capillary tube after fluidizing the coupling medium, whereby the optical fibers are coupled.
A connection structure of a light transfer medium includes: a light transfer medium embedded in a structural body; and a protection tube in which the light transfer medium is inserted. The protection tube is embedded in the structural body at one end portion of the structural body. One end portion of the light transfer medium is inserted into the protection tube such that an end of the one end portion of the light transfer medium is positioned inwardly from one end face of the one end portion of said structural body.
