All-optical clock recovery from NRZ data of 10 Gb s

Abstract

We demonstrate successfully an all optical clock recovery scheme based on all-fiber devices from nonreturn-to-zero format data of 10 Gb/s with a stabilized asymmetric Mach-Zehnder interferometer and a mode-locked erbium-doped fiber laser. This all-optical clock recovery method will find application in ultrahigh-speed all-optical communication systems.
