Reference free Chi 3 dispersion measurements in planar tantalum pentoxide waveguides

Record type: Article

We utilize analysis of third harmonic generation under femtosecond pulsed excitation as a reference free measurement method for third order nonlinear susceptibility (? (3) or “Chi 3”) of planar waveguides. We investigate ? (3) dispersion in planar Ta2O5 waveguides at wavelengths either side of the telecoms window, obtaining a nonlinear coefficient of 2 ×10?13 esu, at 1550 nm. Our study indicates that ? (3) increases within the measured wavelength range due to a threephoton resonance of Ta2O5 electrons, revealing the potential of this material system in high speed integrated nonlinear optical switches for the telecommunications spectral window.
