Abstract
We report on the dispersion of the third-order nonlinear susceptibility ( or “Chi 3”) in planar 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 and obtain a large nonlinear coefficient, , at . Our observation of efficient third-harmonic generation in waveguides in the telecoms window reveals the potential of this material system in high-speed integrated nonlinear optical switches.
