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.展开更多
