100-GHz wavelength-tunable all-optical clock recovery with Fabry-Perot filter and semiconductor optical amplifier

We experimentally demonstrated 100-GHz wavelength tunable clock recovery from 100-Gb/s RZ-OOK signal utilizing a wavelength-converter based on semiconductor optical amplifier (SOA), followed by a Fabry-Perot (FP) filter and a subsequent SOA equalizer. Wavelength-tunable 100-GHz optical clock extraction has been demonstrated from 1542 nm to 1565 nm. Stable optical clocks with a timing jitter of ~250 fs, a pulsewidth of ~3 ps, and an amplitude fluctuation of less than 10% were obtained for all the wavelengths.
