Record type: Article


We report on the dispersion of the third-order nonlinear susceptibility ("chi 3") in planar Ta2O5 waveguides in the telecommunications spectral window. We utilize the observation of third-harmonic generation under ultrashort pulsed excitation as a reference-free characterization method of chi 3 and obtain a large nonlinear coefficient, 2×10^-13?esu, at 1550?nm. Our observation of efficient third-harmonic generation in Ta2O5 waveguides in the telecoms window reveals the potential of this material system in high-speed integrated nonlinear optical switches.
