Optical Phase Erasure and Wavelength Conversion Using Silicon Nonlinear Waveguide With Reverse Biased PIN Junctions

We demonstrate the optical phase erasure and wavelength conversion based on the nontransparency four-wave mixing simultaneously using the integrated silicon waveguide with reverse biased PIN junction. By optimizing the design of the waveguide, a conversion efficiency of -12 dB can be achieved with 3-dB conversion bandwidth of 15 nm. For demonstration, the phase information of the phase-shift keying signal at 10 Gb/s is erased. The simulated and measured constellations and eye diagrams validate the successful operation.
