PROBLEM TO BE SOLVED: To make it possible to avert the influence of the Fresnel reflection at connecting end faces even if a refractive index matching gent is not used, to facilitate optical axis alignment and to suppress the light loss in a juncture by inclining the end faces of the ends of optical fibers to a prescribed angle and varying the respective outside diameters thereof. SOLUTION: The respective connecting end faces 1B, 2B of the optical fibers 1, 2 are inclined in the same direction at a prescribed angleθ. The light emitted from the connecting end face 1B of the optical fiber 1 refracts according to the angleθof inclination of the connecting end face 1B and is made incident on the connecting end face 2B of the optical fiber 1. Namely, the state that the optical fibers are connected by having a misalignment component (s) of the optical axis 2A of the optical fiber 2 from the optical axis 1A of the optical fiber 1 is made into the state of the min. connection loss by the optical alignment of the optical fibers 1A, 2A. The outside diameters of the optical fibers 1A, 2A may be determined from the misalignment component of the optical axis. The outside diameters may be determined when the ends of the optical fibers incline at a prescribed angle. |
