A scheme for all-optical enhancement of clock and clock-to-data suppression ratio of nonreturn-to-zero (NRZ) data based on self-phase modulation is proposed and demonstrated. More than 3-dB clock enhancement and 11-dB clock-to-data suppression ratio enhancement has been realized by a semiconductor optical amplifier (SOA) and fiber Bragg grating (FBG) in reflection. Clock enhancement of more than 6 dB is possible using a FBG in transmission. Using this technique, all-optical clock recovery from NRZ data has been demonstrated.
