摘要： A multi-core optical fiber 1A in which a plurality of cores can easily be identified even in the case where they are symmetrically arranged in its section has seven cores 10 to 16, a visual recognition marker 20, and a shared cladding 30 enclosing the seven cores 10 to 16 and the visual recognition marker 20. The cores 10 to 16 and the visual recognition marker 20 extend along the fiber-axis direction. The respective refractive index of the cores 10 to 16 is higher than the refractive index of the cladding 30. The refractive index of the visual recognition marker 20 differs from that of the cladding 30. In the cross-section perpendicular to the fiber-axis, the cores 10 to 16 are arranged such that they have 6-fold rotational symmetry and line symmetry. The visual recognition marker 20 is arranged at a position which breaks such symmetry.

摘要： An optical fiber has a plurality of holes in a cladding around a core, and has a high failure strength and small transmission loss. The core is made of glass. The cladding surrounds the core, and the holes are formed in the cladding so as to extend along a central axis of the fiber. The holes are formed with constant intervals therebetween along a circle centered on the core, and each hole has a substantially circular cross section. The cladding is sectioned into two claddings. A residual stress in an inner region that is inside a circumcircle of the holes is a compressive stress.

摘要： A method for manufacturing a glass body containing bismuth, which can be used for manufacturing an optical fiber having a low background-loss is provided. The method includes depositing a glass micro-particle layer on an inner wall of a glass pipe, consolidating the glass micro-particle layer to form a glass layer, reducing of a diameter of the glass pipe having the glass layer on the inner wall of the glass pipe, and collapsing the glass pipe having been reduced in diameter at the diameter-reducing step so as to form the glass body. At the depositing step, the glass micro-particle layer is formed while an organobismuth compound is being supplied into the glass pipe. At the consolidating step, the glass layer is consolidated while an organobismuth compound is being supplied into the glass pipe. The optical fiber is made by drawing the glass body.

摘要： In an optical fiber coupler making apparatus which makes an optical fiber coupler by thermally fusing a plurality of optical fibers together by use of a heater and then elongating thus thermally fused part, the heater comprises a heating element which is made of zirconia and which has a slit for containing the optical fibers. The inner face of the heating element is preferentially heated due to a characteristic of its material. Consequently, if optical fibers are contained in the fiber receiving slit, then they can be thermally fused at a sufficiently high temperature in a short period of time, whereby reducing mingling of impurities into the optical fiber coupler. Therefore, the heating element made of zirconia is effective as means for preventing impurities from mingling from the outside thereof. Also, performances of the heating element can be maintained over a long period of time even if the optical fibers are thermally fused at a high temperature. Further, the evaporation of impurities, which may adversely affect characteristics of the optical fiber coupler, hardly occurs from the heating element.
摘要翻译：在通过使用加热器将多根光纤热熔合在一起并随后拉伸这样的热熔融部分而制造光纤耦合器的光纤耦合器制造装置中，加热器包括由氧化锆制成的加热元件，用于容纳光纤的狭缝。由于其材料的特性，加热元件的内表面被优先加热。因此，如果在光纤接收狭缝中包含光纤，则可以在短时间内以足够高的温度热熔融，从而减少杂质混入光纤耦合器中。因此，由氧化锆制成的加热元件作为防止杂质从其外部混合的手段是有效的。此外，即使光纤在高温下热熔融，也可以长时间保持加热元件的性能。此外，可能不利地影响光纤耦合器的特性的杂质的蒸发几乎不会从加热元件发生。
