Abstract

Praseodymium (Pr3+)-doped tellurite glasses suitable for planar waveguide device applications at 1.3 μm operation have been fabricated and characterized optically. The maximum phonon band of undoped glasses is at 738 cm-1, and the emission from the Pr3+: 1G43H5 transition is at 1.33 μm wavelength with a spectral bandwidth of 100 nm. The lifetime of the 1G4 level is approx. 24 μs, and the quantum efficiency is approx. 2.6%, which is similar to that in fluorozirconate glasses.
