A simple method for clock recovery

All optical bit clock recovery is one of the key technologies for all optical 3R recovery. In this paper, a simple method applying the combination of Fabry-Perot (F-P) filter and semiconductor optical amplifier (SOA) for clock recovery is proposed. The effect of the F-P filter finesse on the clock r...

Zusammenfassung:	All optical bit clock recovery is one of the key technologies for all optical 3R recovery. In this paper, a simple method applying the combination of Fabry-Perot (F-P) filter and semiconductor optical amplifier (SOA) for clock recovery is proposed. The effect of the F-P filter finesse on the clock recovery and the reduction in the amplitude fluctuation of the clock pulse by the SOA are discussed theoretically. With this technology 10 Gbit/s clock recovery with equal amplitude and wavelength transparency was realized experimentally.
