Abstract : We report the first third order nonlinear characterization of Ge-rich Si 1-x Ge x waveguides, with Germanium concentrations ranging from 0.7 to 0.9. A bi-directional top hat D-Scan method was used to determine the waveguide nonlinear parameters and to deduce the Kerr nonlinear refractive index and the two-photon absorption coefficient at the wavelength of 1.58 µm.
