The optimization of erbium-doped Ta2O5 thin film waveguides deposited by magnetron sputtering is described. Background losses below O.4dB/cm have been obtained before post-annealing. A broad photoluminescence spectrum centered at 1534nm is obtained, and the photoluminescence power and fluorescence lifetime increase with post-annealing, yielding promising results for compact amplifiers.

Abstract
The optimization of erbium-doped Ta2O5 thin film waveguides deposited by magnetron sputtering is described. Background losses below O.4dB/cm have been obtained before post-annealing. A broad photoluminescence spectrum centered at 1534nm is obtained, and the photoluminescence power and fluorescence lifetime increase with post-annealing, yielding promising results for compact amplifiers.File in questo prodotto:
