No full textMicro-structured Er 3+-Tm 3+ co-doped tellurite fiber with three rings of holes was fabricated using a soft glass drawing tower by a stack-and-draw technique. Amplified spontaneous emission (ASE) around 1550nm band were observed when pumped with both, 980nm and 790nm, lasers.6314Russell, P., Photonic crystal fibers (2003) Science, 299, pp. 358-362Knight, J.C., Photonic crystal fibers (2003) Nature, 424, pp. 847-851Kumar, V.V.R.K., George, A.K., Reeves, W.H., Knight, J.C., Russell, P.St.J., Omenetto, F.G., Taylor, A.J., Extruded soft glass photonic crystal fiber for ultrabroad supercontinuum generation (2002) Opt.

Alpejska przestrzeń grozy w opowiadaniu E.F. Bensona
No full textThe Alpine horror space in E.F. Benson’s story The Horror-Horn The article presents the image of the Alps in the work of the British writer Edward Frederick Benson. The author focuses in her reflections on Benson’s story The Horror-Horn, still unpublished in Poland, one of the first works which feature an icon of popular culture: the abominable snowman. In his story Benson depicts the Alps in accordance with a convention typical of horror literature, though the descriptions of mountain peaks have their roots also in the folk tradition or in mythological images. An analysis illustrating Benson’s “Alpine horror” mechanism is complemented by a fragment of The Horror-Horn translated into Polish.The Alpine horror space in E.F.

Magneto-transport In Granular Ribbons At High Magnetic Fields
No full textWe have measured the bulk and surface magnetization and magnetoresistance of granular Co10Cu90 ribbons treated with isochronous anneals, from helium to room temperature and at high magnetic fields. The magnetoresistance of these materials can be larger than 15% at room temperature and at high magnetic fields. We show that interparticle interactions are needed for a complete description of the experimental results.1964547Levy, P.M., (1995) J. Magn. Magn.

Development Of Soft-glasses Photonic Crystal Fiber Made By Stacking-and-draw Technique
No full textWe have been able to produce soft glass conventional core-clad and micro-structured fibers using rod-and-tube and stack-and-draw method respectively. The stack-and-draw technique shows several difficulties when used with soft glasses, that we managed to avoid using two different lead and alkaline glasses. Non commercial glasses and fibers were thermo-mechanically and optically characterized.6469White, T.P., McPhedran, R.C., de Sterke, C.M., Botten, L.C., Steel, M.J., Confinement losses in micro structure optical fibers (2001) Opt.
