All-optical clock and data recovery using self-pulsating lasers for high-speed optical networks

All-Optical Clock and Data Recovery (OCDR) is an important function for future optical networks and optical signal processing. The OCDR realizes a long-distance optical data transmission system by restoring the incoming data and then retransmitting. The Self-Pulsating (SP) lasers are the promising technologies to enable fast and high-speed data recovery system in an optical domain. In this paper, we design and implement the OCDR based on two SP laser types, Amplified Feedback Laser (AFL) and Distributed Bragg Reflector Laser (DBRL). A comparative study and measurement of the network performance for the two types have been presented.
