The nonlinear optics of Si photonic wires is discussed. The distinctive features of these
waveguides are that they have extremely large third-order susceptibility χ^(3) and dispersive …

We demonstrate broadband wavelength conversion of a 40 Gb/s return-to-zero signal using
four-wave-mixing (FWM) in a dispersion engineered chalcogenide glass waveguide. The 6 …

We demonstrate optical 2R regeneration in an integrated silicon device consisting of an 8-
mm-long nanowaveguide followed by a ring-resonator bandpass filter. The regeneration …

A novel scheme for an ultrahigh-speed all-optical half adder based on four-wave mixing
