  • Publication number: 20150212387
    Abstract: A device for the generation of supercontinuum in infrared fiber with a pump light comprising a microchip laser operating with a wavelength of 1.0 ?m or greater that can be wavelength shifted though a nonlinear element to a wavelength beyond the two-photon absorption of the infrared fiber and launched into infrared fiber whereby the spectrum is broadened in the infrared fiber through various nonlinear processes to generate a supercontinuum within the mid-IR from 2 to 14 ?m.

  • Patent number: 7283712
    Abstract: This invention pertains to a glass fiber, a Raman device and a method. The fiber is a hollow core photonic bandgap chalcogenide glass fiber that 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. The device includes a coupler for introducing at least one light signal into a hollow core of a chalcogenide photonic bandgap fiber; a hollow core chalcogenide photonic bandgap glass fiber; a microstructured fiber region disposed around said core; a solid fiber region disposed around said microstructured region for providing structural integrity to said microstructured region; and a Raman active gas disposed in the hollow core.

  • Patent number: 6015765
    Abstract: A telluride glass with glass transition temperature above 150.degree. C., fference between the crystallization temperature and the glass transition temperature of above 200.degree. C., and extended transmission in the infrared region of radiation of up to 20 microns having, on mol basis, 20-60% tellurium, 10-50% arsenic, 4-35% germanium, 0.5-15% gallium, up to 15% iodine, and up to 30% selenium. All or part of the gallium can be replaced with indium and the glass can contain up to 5%, based on the weight of the glass components, of a rare earth ion to render the glass fluorescent. Optical fibers drawn from these glasses have shown mid infrared fluorescence and may have as a bright source of IR light.
