Abstract

40Gbit/s all-optical 3R regeneration was demonstrated. The wavelength of the data signal was converted with an SOA by cross-gain modulation (XGM). The clock recovery was based on Fabry-Perot (F-P) filter of high finesse (F=1000). The actual bit rate of the data signal was 40.04796Gbit/s, matching the free spectral range (FSR) of the F-P filter. Two SOAs were used in series as the decision gate to make full use of the nonlinearity. Taking advantage of the chirp, one narrowband OBF was used to reshape the waveforms in the clock recovery, so as to reduce the pattern effect. Another narrowband OBF was used after the decision gate to diminish the tails of the pulses. The clock signal had a root mean square (RMS) timing jitter of around 843fs. The output data signal of the regenerator had an optical signal-to-noise ratio (OSNR) of more than 40dB/0.1nm. The maximum timing jitter was 1.439ps.
