摘要： An optically active device comprising an optical fiber, a light source and an optical device is disclosed. The optical fiber comprises a core made of an optical functioning glass doped with Pr.sup.3+ as an active ion and transmits light at a first wavelength. The light source generates excitation light at a second wavelength shorter than the first wavelength. The optical device directs the excitation light from the light source into the optical fiber. Then, Pr.sup.3+ in the core of the optical fiber is stimulated to emit light at the second wavelength. As a result, an optical function such as optical amplification can be effected at the second wavelength.

摘要： There is provided a method of producing a protective metal coated or covered superconducting ceramic wire by applying a finely pulverized protective metal-dispersed polymeric resin onto the surface of a glass wire in amorphous state of metal oxides capable of being converted into superconductive ceramic, heating the wire to remove the polymeric resin therefrom to obtain the wire having a metal powder coating thereon, and heat-treating the wire to become superconductive. The coating is easily conducted without damaging the excellent productivity of the so-called melt-quenching and preform wire-drawing process for producing a superconducting ceramic wire.

摘要： An optically active device comprising an optical fiber, a light source and a coupler is disclosed. The optical fiber has a core made of a silicate glass containing Rb and/or Cs oxide. The core is doped with Nd.sup.3+ as an active ion and transmits light at 1.3 .mu.m band. The light source generates excitation light at 0.8 .mu.m. The coupler directs the excitation light from the light source into the core of the optical fiber. A signal light or a spontaneous light at 1.3 .mu.m band which is transmitted in the core stimulates Nd.sup.3+ to emit light at 1.3 .mu.m band. As a result an optical function such as optical amplification can be effected at 1.3 .mu.m band.

摘要： A superconducting ceramic wire is prepared from a superconducting ceramic-forming oxide composition by melting, the composition and quenching the melt to form a dense glass, which is soften and wire-drawn in a furnace. The resulting wire is heat-treated to form crystals and made into a superconducting ceramic wire. The wire has a flexibility and remarkable superconductivity which can further be improved by applying pressure to be made more dense and repeating the heat-treatment.

摘要： A superconducting ceramic wire is produced by melting a superconducting ceramic-forming metal oxide composition, and quenching the melt into a glass which is then formed into a preform of thin plate. The preform is soften and wire-drawn without causing crystallization in a furnace into a flexible elongated thin tape having a thickness of e.g. 40 to 60 .mu.m. The tape is heat-treated for crystallization to obtain the superconducting wire. The disclosure mentions mainly Bi Bi-Sr-Ca-Cu-O superconducting systems.

摘要： An optical functioning glass for enabling optical amplification at 1.3-.mu.m wavelength band or increasing efficiency of the amplification is disclosed. The optical functioning glass contains Nd.sup.3+ as an active material and uranium, both of which are doped in a multi-component function glass serving as a host glass. Since uranium is doped in the optical functioning glass, light emission of Nd.sup.3+ in the 1.06-.mu.m wavelength band can be absorbed by uranium. A decrease in efficiency of induced emission in a 1.3-.mu.m wavelength band can be prevented, and an optical functioning glass suitable for optical amplification in the 1.3-.mu.m wavelength band can be obtained. When a fiber is formed using the optical functioning glass as a core, a low-threshold, high-gain fiber amplifier, fiber laser, and the like can be obtained.

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.
