Determination of nonlinear refractive index in a Ta2O5 rib waveguide using self-phase modulation

Tai, Chao-Yi, Wilkinson, James S., Perney, Nicholas M.B., Netti, M.C., Cattaneo, F., Finlayson, Chris and Baumberg, Jeremy (2004) Determination of nonlinear refractive index in a Ta2O5 rib waveguide using self-phase modulation Optics Express, 12, (21), pp. 5110-5116.

Record type: Article


Self-phase modulation has been observed for ultrashort pulses of wavelength 800nm propagating through a 1 cm-long Ta2O5 rib waveguide. The associated nonlinear refractive index n2 was estimated to be 7.23×10-19 m2/W, which is higher than silica glass by more than one order of magnitude. Femtosecond time of flight measurements based on a Kerr shutter configuration show that the group velocity dispersion is small at a wavelength of 800 nm, confirming that dispersion may be neglected in the estimation of n2 so that a simplified theory can be used with good accuracy.
