Abstract :
Line rate optical clock recovery at 160-Gb/s has been demonstrated based on injection-locking and optical time-division multiplexing of a 40-GHz regeneratively mode-locked laser diode (RML-LD). Injection-locking is achieved by directly coupling the 160-Gb/s data streams to a photodetector in the RML-LD feedback loop. The pulsewidth and root-mean-square timing jitter of the recovered clocks are 2.31 ps and 225 fs (10 Hz-40 MHz), respectively
