Description/Abstract
We report on the dispersion of the third-order nonlinear susceptibility (��3� or “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 ��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
