Picosecond third-order nonlinearity of lead-oxide glasses in the infrared
Get PDFHeavy metal-oxide glasses containing lead and bismuth were prepared, and their picosecond third-order nonlinear (NL) optical characteristics were investigated. NL refractive indices of ≈ 10−18 m2/W at 1064 nm were measured. Negligible NL absorption was verified and, as a consequence, the samples present a good factor-of-merit for photonic applications

Full text linkProduction and Characterization of Carbon Thin Films by the Magnetron Sputtering Technique
Full text linkCarbon thin films were produced by the magnetron sputtering technique. The deposition of the carbon films was performed on Co buffer-layers previously deposited on c-plane (0001) sapphire substrates. The samples were thermally treated under vacuum conditions and characterized by Raman spectroscopy, scanning electron microscopy (SEM) and X-ray diffraction (XRD). The XRD peak related to the carbon film was observed and the Raman spectroscopy indicated a good degree of crystallinity of the carbon film.</jats:p
