We report a wavelength-tunable clock recovery scheme for all-optical 3R regeneration and simultaneous wavelength conversion. The scheme is based on a fiber-optic parametric oscillator, in which dynamic gain results from the fourwave mixing process in the fiber. In our implementation, 2.9 ps clock pulses are recovered from the incident pseudo-random data stream with the clock wavelength being tunable over the whole erbium-doped-fiber-amplifier bandwidth. RF spectrum measurements show that the recovered clock has less timing jitter than the incident data stream. We also present a two-channel clock recovery experiment, which demonstrates the feasibility of our scheme at 100 Gbit/s data rate.
