Abstract :
The nonlinear of a nanoscale Brillouin-active silicon waveguide is examined through heterodyne four-wave mixing experiments. The interference between Brillouin scattering, Kerr, and dispersive free-carrier nonlinearities are analytically described to explain the characteristic line-shapes observed.
