    摘要： The present invention is generally directed to a bulk barium copper sulfur fluoride (BCSF) material made by combining Cu2S, BaS and BaF2, heating the ampoule between 400 and 550 ° C. for at least two hours, and then heating the ampoule at a temperature between 550 and 950 ° C. for at least two hours. The BCSF material may be doped with potassium, rubidium, or sodium. The present invention also provides for a BCSF transparent conductive thin film made by forming a sputter target by either hot pressing bulk BCSF or hot pressing Cu2S, BaS and BaF2 powders and sputtering a BCSF thin film from the target onto a substrate. The present invention is further directed to a p-type transparent conductive material comprising a thin film of BCSF on a substrate where the film has a conductivity of at least 1 S/cm. The substrate may be a plastic substrate, such as a polyethersulfone, polyethylene terephthalate, polyimide, or some other suitable plastic or polymeric substrate.

    摘要： A thermally stable chalcogenide glass, a process for making the same, and an optical fiber drawn therefrom are provided. A chalcogenide glass having the composition Ge(5−y)As(32−x)Se(59+x)Te(4+y) (0≦y≦1 and 0≦x≦2) is substantially free from crystallization when it is heated past the glass transition temperature Tg or drawn into optical fibers. A process for making the thermally stable chalcogenide glass includes purifying the components to remove oxides and scattering centers, batching the components in a preprocessed distillation ampoule, gettering oxygen impurities from the mixture, and heating the components to form a glass melt. An optical fiber formed from the chalcogenide glass is substantially free from crystallization and exhibits low signal loss in the near-infrared region, particularly at wavelengths of about 1.55 μm.

    摘要： A hollow core photonic bandgap chalcogenide glass fiber includes a hollow core for passing light therethrough, a Raman active gas disposed in said core, a microstructured region disposed around said core, and a solid region disposed around said microstructured region for providing structural integrity to said microstructured region. A coupler can introduce at least one light signal into the hollow core of the chalcogenide photonic bandgap fiber. The method includes the steps of introducing a light beam into a hollow core chalcogenide photonic bandgap glass fiber filled with a Raman active gas disposed in the core, conveying the beam through the core while it interacts with the gas to form a Stokes beam of a typically higher wavelength, and removing the Stokes beam from the core of the fiber.
