Multichannel wavelength conversion is experimentally demonstrated for high-speed 128 Gb/s dual-polarization quadrature phase-shift keying signals using four-wave mixing in a polarization diversity circuit with silicon nanowires as nonlinear elements. The wavelength conversion performance is investigated for both single-and three-channel input signals, showing quality factors well >9.8 dB (corresponding to bit-error-ratios better than 10(-3)) and with a negligible power penalty compared with the back-to-back case.
