摘要
A non-return-to-zero （NRZ） to pseudo-return-to-zero （PRZ） converter consisting of a semiconductor optical amplifier （SOA） and an arrayed waveguide grating （AWG） is proposed, by which the enhancement of clock frequency component and clock-to-data suppression ratio of the XRZ data are evidently achieved. All- optical clock recovery from XRZ data at 10 Gb/s is successfully demonstrated with the proposed XRZ-to- PRZ converter and a mode-locked SOA fiber laser. Furthermore, XRZ-to-RZ format conversion of 10 Gb/s is realized bv using the recovered clock as the control light of terahertz optical asymmetric demultiplexer （TOAD）, which further proves that the proposed clock recovery scheme is applicable.
