All-optical timing extraction using a 1.5 mu m self pulsating multielectrode DFB LD

All-optical timing extraction from an intensity modulated 196 Mbit/s return to zero optical data stream by the injection locking technique, using a 1.5μm self-pulsating multielectrode DFB LD is demonstrated. A frequency lock-in range, which depends upon both the injection signal level and the length of space continuation is investigated.
