Abstract :
The authors demonstrate an all-optical clock recovery scheme from non-return-to-zero format data, with an asymmetric Mach-Zehnder interferometer and a mode-locked Er-doped fibre laser. Since this scheme consists of an all-fibre device, the clock recovery bandwidth can extend to the terahertz region. Such all-optical clock recovery techniques will find application in ultra-high speed all-optical communication systems
