All-optical wavelength conversion and multicasting for polarization-multiplexed signal using angled pumps in a silicon waveguide.
We report all-optical wavelength conversion and multicasting for a 20 Gb/s (2×10 Gb/s) polarization-multiplexed (Pol-MUX) nonreturn-to-zero amplitude-shift keying signal using four-wave mixing (FWM) in a silicon waveguide. The temporal waveforms and eye diagrams demodulated from both polarization channels of the converted idler are clearly observed. Moreover, the wavelength multicasting of the Pol-MUX signal is also demonstrated by using two incident pumps.
