- Abstract
Er3+-doped Li2O-SrO-ZnO-Bi2O3 (LSZB) glasses that are suitable for optical amplifier applications have been fabricated through the conventional melt-quenching method, and the spectroscopic properties of Er3+ in the glasses were characterized. The density, the refractive indices, the optical absorption, the Judd–Ofelt parameters t, and the spontaneous transition probabilities of the glasses were measured and calculated. The Raman spectrum shows three strong peaks, at 255, 382, and 491cm-1. The emission peak from the Er3+: 4I13/2 4I15/2 transition locates around 1.53-µm with a full width at half maximum (FWHM) of ~78 nm. The theory lifetime of the 4I13/2 level is ~2.85ms. The emission cross section is estimated to be ~9.76×10-21 cm2, which is larger than those of silicate glasses. In sum, the above results indicate that the LSZB glass is a promising host material for applications in optical amplifiers.
