Broadband 1.5- μm emission of high erbium-doped Bi 2O 3-B 2O 3-Ga 2O 3 glasses
Abstract
High Erbium-doped glass showing the wider 1.5-μm emission band is reported in the Bi 2O 3-B 2O 3-Ga 2O 3 system and its thermal stability and optical properties such as absorption, emission spectra, absorption and stimulated emission cross-sections and fluorescence lifetime are investigated. Compared with other glass hosts, the gain bandwidth properties of high Er 3+ content in BBG glass are better than those of tellurite, germanate, silicate and phosphate glasses. The broad and flat 4I 13/2→ 4I 15/2 emission and the larger stimulated emission cross-section of Er 3+ ions around 1.5 μm enable it to be used as a host material for potential broadband optical amplifiers at C and L bands in the microchip configuration.
