Abstract

Guided-wave absorption and fluorescence in epitaxial Er:BaTiO3 thin film channel waveguides on MgO are reported. Guided-wave absorption is strongly dependent on post-growth annealing. Stimulated emission over a 40 nm bandwidth (λcenter ≈ 1.54 μm) has been achieved in oxygen-annealed waveguides. At 1.54 μm the absorption is reduced from ≈ -2 dB/cm to ≈ -1.3 dB/cm in a 2.2 mm long 5 μm wide channel waveguide due the presence of the pump light.
