Abstract

We describe the fabrication and characterization of micron-scale buried strip waveguides with erbium-doped (~ 1 at. %) silicon monoxide (SiO) cores and SiO2 and polymer claddings. In spite of large core-cladding index offset (Δn~0.4), propagation loss is as low as ~ 1 dB/cm. The crosssection for the 4I13/2 to 4I15/2 erbium transition was estimated as ~10-20 cm2, a factor of 2 to 3 higher than in silica glass. The annealed core material contains a high density of amorphous silicon nanoclusters, which act as efficient broadband sensitizers for erbium. Both a traditional copropagating pump (980 nm wavelength) configuration and a transverse pump (532 nm wavelength, < 10 W/cm2) configuration were tested. In either case, free carrier absorption loss is the dominant pump-induced mechanism and approximately 15–20 % of the erbium population is invertible.
