Abstract

Erbium-doped Y₂O₃ planar optical waveguides have been fabricated by spray-pyrolysis deposition. The attenuation spectrum of the waveguide shows peaks that are due to absorption of the erbium ions. The as-deposited layers also show photoluminescence sharply peaking at 1540 nm with additional Stark splitting. The thin layers of Er³⁺:Y₂O₃ obtained are promising for the realization of integrated-optic amplifiers and lasers.
