All optical clock recovery has been experimentally demonstrated by an actively mode‐locked fiber ring based on the semiconductor optical amplifier (SOA) from a 10‐Gb/s NRZ data stream. The system exploits the cross‐gain modulation (XGM) nonlinear effect in SOA, and a Fabry–Perot etalon suitably inserted in the loop improves the mode‐locking stabilization and efficiency. © 2004 Wiley Periodicals, Inc.
