Abstract

An optical fiber with erbium ions doped in a Ta2O5-Al2O3-SiO2 glass was fabricated by modified chemical vapor deposition process along with an aerosol delivery technique. The effects of Ta2O5 on the spectroscopic properties of the erbium ions in the glass host have been studied for an application in optical amplifiers. The ground state absorption spectra for the pump bands, 4I15/24I11/2, 4I15/24I9/2, 4I15/24F9/2, and the gain band, 4I15/24I13/2, of erbium ions were measured and compared with those in aluminosilicate hosts. The excited state absorption 4I13/22H11/2, 4S3/2 around 800 nm and subsequent upconversion fluorescence around 500 nm were also investigated. Furthermore backward amplified spontaneous emission in the 1.5 μm region was measured for various pump wavelengths and intensities. Differences in spectroscopic features of erbium ions in these glasses compared with aluminosilicate glass containing erbium ions were attributed to Ta2O5 doping providing a lower local symmetry of crystal fields around erbium ions.
