## Abstract A new but simply implemented allโoptical clock enhancement scheme for nonreturnโtoโzero (NRZ) data streams utilizing a semiconductor optical amplifier (SOA) and a chirped fiber Bragg grating (CFBG) is presented. The clockโtoโcarrier suppression ratio is highly improved by more than 23 d
