Abstract

Guided wave absorption and fluorescence measurement were presented from epitaxial Er:BaTiO₃ films grown on MgO. The guided wave Er fluorescence had a full width at half maximum (FWHM) similar to that from Er doped glass with a peak emission at 1534 nm. The guided wave absorption spectrum showed an absorption peak at 1440 nm that was attributed to the second harmonic of an O-H bond resonance. Photoluminescence decay transient measurements indicate that the Er luminescence has an efficiency of 76%. The Er relaxation is dominantly radiative, however, some competing Er relaxation mechanisms are present in the Er:BaTiO₃ film.
