All-optical wavelength conversion for 10 Gb/s DPSK signals in a silicon ring resonator.

We demonstrate all-optical wavelength conversion at 10 Gb/s for differential phase-shift keyed (DPSK) data signals in the C-band, based on four-wave mixing (FWM) in a silicon ring resonator. Error-free operation with a system penalty of ~4.1 dB at 10⁻⁹ BER is achieved.
