摘要：

Using a 4-mm-long compact silicon-nanowire waveguide, we demonstrated nonlinear-optic effects such as the spectral broadening of optical short pulses due to self-phase modulation and nonlinear transmittance due to two-photon absorption. At a 12W input power level, we observed a 1.5-pi nonlinear phase shift and a strong saturation of optical output power in a sample. We also estimated the third-order nonlinear coefficient 112 and the two-photon absorption coefficient beta, and compared them with those previously reported.
