Abstract
The emission at 1530 nm and its applications in optical communicationsare discussed. The efficient width of the emission band Δeff,which is up to 91 nm, is larger as compared with silica-based glass,bismuth glass and ZrF4–BaF2–LaF3–AlF3–NaF(ZBLAN) glass doped by Er3+ ions. Under the excitation of 785 nmlaser, the emission integral intensity of 1530 nm increases about fivetimes in the glass ceramics higher than that in the glass. This isexplained by the quantum cutting process by two-photon emission withphonon assistance. The results indicate that the glass ceramics are apromising candidate for developing broadband optical amplifiers inwavelength-division multiplexed systems.
