Erbium-Doped Fibers Based on Cesium–Silicate Glasses

Using modified chemical vapor deposition and solution doping techniques, erbium-doped fibers (EDFs) were prepared based on cesium–silicate glasses. The possibility of manufacturing high-concentration (1–13 wt%) EDFs was shown, and a fiber structure was realized by means of direct doping of cesium–si...

Description
Summary:Using modified chemical vapor deposition and solution doping techniques, erbium-doped fibers (EDFs) were prepared based on cesium–silicate glasses. The possibility of manufacturing high-concentration (1–13 wt%) EDFs was shown, and a fiber structure was realized by means of direct doping of cesium–silicate glass with erbium ions. The optical, fluorescence, and gain properties of prepared samples were examined. A maximum gain of 25 dB at 1538 nm was achieved in the fiber at an optimum length of 30 cm at a pump power of 50 mW at 979 nm.
