摘要：

A novel scheme of all-optical clock recovery from mutiwavelength non-return-to-zero (NRZ) data stream is proposed and demonstrated. The chirp induced by a chirped fibre Bragg grating and a semiconductor optical amplifier is used to enhance the clock. The clock is recovered after injecting the enhanced signal into the scheme based on the stimulated Brillouin scattering. The experiment is carried out and the dual-wavelength clock is recovered. This novel scheme can realize clock recovery of multiwavelength NRZ signal in the total wavelength range of 3.3 nm. This clock recovery technology is transparent to the data bit rate and modulation for-mat, also without pattern dependence.
