摘要： PROBLEM TO BE SOLVED: To provide an inexpensive mechanical splice capable of preventing the loss of an optical fiber from increasing.
SOLUTION: The mechanical splice 1 is provided with a guide groove substrate 4 having a guide groove 3 which is used to guide opposing optical fibers 2 so that they are pushed against each other and to conduct positioning and core adjusting, a pressing substrate 6 having a pressing surface 5 to press the fibers 2 being inserted in the groove 3 and an optical fiber holding member 7 which is used to hold the substrates 4 and 6 so as to hold the fibers 2. In the mechanical splice 2, the fibers 2 are spliced by filling refractive index matching member 11 in the vicinity of the fiber pushed section. A housing section 15 is formed on at least either one of the substrate 4 facing the pushed section of the fibers or the substrate 6 to house the member 11.

摘要： PROBLEM TO BE SOLVED: To provide a reliable mechanical splice.
SOLUTION: Opposed optical fibers 2a and 2b are butted and connected in the state where coated optical fiber 2aa and 2ba at the tip part are bent. Because each coated optical fiber 2aa and 2ba comes into contact with either a V-grooved substrate 4 or a presser foot substrate 5, bending does not advance from an initial state, and optical loss is not increased. Thereby, the breaking of wire of the optical fibers 2a and 2b is prevented, and the initial state is maintained with high reliability.

摘要： PROBLEM TO BE SOLVED: To provide a mechanical splice which can maintain an initial connecting state.
SOLUTION: The cross-sectional shape of a V-grooved substrate 4 and a presser foot substrate 5b which are positioned at a coated clamping part is formed in a non-circular form. Accordingly, when an optical fiber 2 butted and connected by the mechanical splice 1 is twisted in a circumferential direction by external force, the surface of the coated part of the optical fiber 2 is fitted to the V-grooved substrate 4 and the presser foot substrate 5b, thereby the optical fiber 2 is not twisted more than a fitted state. The breaking of wire of a coated optical fiber 7 in the optical fiber 2 is prevented, and the initial connecting state is maintained with high reliability.

摘要： PROBLEM TO BE SOLVED: To provide a connector for a photonic crystal optical fiber, which dust or the like near its end face is prevented from entering its circular opening during and after the polishing and which is easily cleaned, and also to provide its manufacturing method. SOLUTION: The photonic crystal optical fiber 302 which is inserted into and fixed to a connector ferrule 306 is solid near its end face; therefore, no abrasive material nor polishing dust enters the circular opening 303 through the end face 302a, thereby causing no damage nor shear drop. In addition, dust stuck after the polishing is prevented from entering the circular opening 303 through the end face 302, with the cleaning made easy. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a waveguide type grating element which has high reliability and has characteristics independent of temperature change and requires a shorter manufacturing time. SOLUTION: The stress accompanied with deformation of a metallic plate 13 during temperature change is stopped from being transmitted to a quartz substrate 11 by an intermediate member 12 which has a breaking strength higher than that of the quartz substrate 11, by inserting the intermediate member 12 between the quartz substrate 11 and the metallic plate 13 to give a three-layered structure, so that the quartz substrate 11 is prevented from being broken and characteristics are made independent of temperature change to improve the reliability. Since it is unnecessary to grind the quartz substrate 11, the manufacturing time is shortened. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a photonic crystal optical fiber durable against bending from the viewpoint of transmission loss, strength and reliability and usable for connecting parts of conventional optical fibers. SOLUTION: Tensile strain due to bending can be decreased by using quartz for the core 3 and a clad 2 and by making the outer diameter of the clad 2 smaller than the outer diameter (125 μm) of a standard optical fiber. For example, by controlling the outer diameter of the clad 2 comprising quartz to 60 μm, the tensile strain is 0.002 even when the bending radius is decreased as small as 15 mm, which suppresses the strain to an almost equal level to that of conventional optical fibers. By forming resin coating layers 5 to 7 around the clad 2 to make the outer diameter of 125 μm, connecting parts such as connectors and mechanical splice for conventional optical fibers can be used.

摘要翻译：解决的问题：从传输损耗，强度和可靠性的观点出发，提供耐弯曲的光子晶体光纤，并且可用于连接常规光纤的部件。解决方案：通过使用石英作为芯3和包层2，并且通过使包层2的外径小于标准光纤的外径（125μm），可以减少由于弯曲引起的拉伸应变。例如，通过将包含石英的包层2的外径控制为60μm，即使当弯曲半径减小到15mm时，拉伸应变为0.002，从而将应变抑制到与常规光学器件几乎相等的应变纤维。通过在包层2的周围形成树脂被覆层5〜7使外径为125μm，可以使用连接部件，例如连接器和常规光纤的机械接合。版权所有（C）2004，JPO
