    摘要: A polarization-maintaining photonic crystal fiber 10 includes six thin holes 4a and 4b adjacent to a core 1. Among these holes 4a and 4b, a pair of holes 4b at opposite sides of the core 1 have a diameter greater than that of the other four thin holes 4a, and therefore, the polarization-maintaining photonic crystal fiber 10 has polarization-maintaining ability. An overclad layer 3 exists around the clad layer 2 which includes a large number of thin holes 4a and 4b around the core 1. The overclad layer 3 includes a pair of marking portions 5 at opposite sides of the core 1. The marking portions 5 are holes which can be seen at positions different from the clad layer 2 when the fiber 10 is viewed from a position right above the fiber 10 in the drawing. In this way, the direction of the polarization plane of the polarization-maintaining photonic crystal fiber 10 is identified.

    摘要: A 1.55 μm band dispersion shifted optical fiber is provided which has a low loss and low dispersion slope. A core region “a” is heavily doped with GeO2 . A core region “b” is composed of pure SiO2 glass. A cladding section is arranged around the core region. The cladding section has a lot of holes extending in the longitudinal direction of the optical fiber. The holes of the cladding section are not located at random, but have a honeycomb structure composed of regular hexagons which have a side length of Λ, and serve as a primitive lattice. The center of the core section has a region having a refractive index higher than that of the periphery of the core section. The core section has the refractive index distribution in which the group velocity dispersion at the operation wavelength of the region becomes the normal dispersion.

    摘要: An optical fiber connection structure which reduces MPI in the use of an optical fiber with a bend resistance improved by forming holes in the fiber, and a single-mode fiber which reduces MPI are provided. A second cladding portion of a second single-mode fiber 20 includes holes 28, and thus, the second single-mode fiber 20 has low bending loss. A portion of the second single-mode fiber 20 connected to a first single-mode fiber 10a is made solid by filling corresponding portions of the holes 28 over the length L0, and light in a mode LP11 is significantly attenuated in this portion, thereby reducing MPI.

    摘要: In a suctioning state, even if the amount of dust trapped in a dust collecting unit in a main air passage is increased, air suctioned from a hose connection port is branched into a first half passage and reduction in the suction air amount can be suppressed. When the suctioning state is switched to a dust moving state by switch means, the dust trapped in a pleated filter is moved to the dust collecting unit, increase in the air passage resistance at the first half passage side caused by clogging of the pleated filter can be suppressed, and reduction in suction power over time can be suppressed. Since an upper air passage and lower air passage are provided in the lid body, the dust collecting unit is exposed with the lid body opened, whereby maintenance performance of the dust collecting unit is improved.
