Erbium- and Magnesium-codoped Silica-Based Transparent Glass Ceramic Core Fiber Made by FCVD and Flash Vaporization
نویسندگان
چکیده
A fiber made by Furnace CVD was codoped with Erbium and Magnesium using a Flash Vaporization System for the first time. The fiber core is spontaneously formed as a Transparent Glass Ceramic (TGC). Due to the small nanoparticle size (<50 nm) and high volumetric density (10~10 m), the optical loss due to scattering is as low as < 0,6 dB/m. Erbium ions are highly concentrated within phase-separated nanoparticles. We study the absorption and emission properties of Erbium around 1.55 μm in this TGC-core fiber. OCIS codes: (060.2270) Fiber characterization; (060.2290) Fiber materials; (160.4236) Nanomaterials; (160.5690) Rareearth-doped materials; (160.6030) Silica.

Erbium-doped nanoparticles in silica-based optical fibres
Developing of new rare-earth (RE)-doped optical fibres for power amplifiers and lasers requires continuous improvements in the fibre spectroscopic properties (like shape and width of the gain curve, optical quantum efficiency, resistance to spectral hole burning and photodarkening,...). Silica glass as a host material for fibres has proved to be very attractive. However some potential applicati...

متن کاملIntense red upconversion luminescence from Tm3+/Yb3+ codoped transparent glass ceramic.
Tm3+/Yb3+ codoped transparent glass ceramic containing β-PbF2 nanocrystals was successfully prepared. After thermal treatment, emissions from the state of Tm3+ excited by 980 nm laser were greatly quenched by cross relaxation and the 700 nm luminescence from Tm3+:3F2,3→3H6 transition was strongly enhanced. A nearly monochromatic red luminescence band was observed. Based on the luminescence deca...

Ho(3+)/Yb(3+) codoped glass ceramic was prepared by melt-quenching and subsequent thermal treatment. Under a 980 nm diode laser excitation, upconversion emissions from Ho(3+) ions centered at 540, 650, and 750 nm were greatly enhanced compared with those in the precursor glass. Especially, the short-wavelength upconversion emissions centered at 360, 385, 418, 445, and 485 nm were successfully o...
