Abstract
The nonlinear propagation characteristics of multiwavelength optical signals in silicon waveguides are investigated for all-optical regeneration. Our experiment and simulation show that the multiwavelength regenerators based on silicon waveguides can be developed with a clock-pump scheme by properly setting the signal and pump power levels, ensuring that the Q -factor degradation induced by the Kerr nonlinear cross talk of the input signals is < 1.0    dB and the clock-pump power is no more than the saturated input level related to the nonlinear loss. A three-wavelength regeneration experiment based on the clock-pump four-wave-mixing scheme was demonstrated in the silicon nanowire waveguide, and both the extinction ratio and Q -factor are improved by > 3.0    dB for 12.5    Gbit / s on–off keying signals. The feasibility of an eight-wavelength regeneration with the clock pump is also verified by simulation.
