abstract

  • Erbium-doped germanosilicate glasses with various cerium ions contents have been prepared. Optical absorption and 1.53 m emission spectra were measured to characterize the spectroscopic performances of prepared samples. A detailed study of 1.53 m spectroscopic properties was carried out when pumped by an 808 nm laser diode. Moreover, an energy level diagram and an energy transfer mechanism between Er3+ and Ce3+ were proposed to elucidate the enhanced 1.53 m fluorescence. It is found that the prepared samples have optimal spectroscopic properties when the Ce3+ concentration is fixed to 0.5 mol. %. High spontaneous radiative transition probability (172.66s(-1)), large effective emission bandwidth (74 nm), and emission cross section (9.4910(-21)cm(2) indicate that 808 nm pumped Er3+/Ce3+ codoped germanosilicate glass might be a suitable material for a broadband optical amplifier.
