Abstract :
The 2nd-order fractional Talbot effect is employed to multiply the 10-GHz optical pulse-train injection for 4th-order ration-harmonic-mode-locking of a SOA fiber laser at 40-GHz. With improved modulation-depth by enlarging pulse-extinction-ratio from 0.55 to 2.3, the SOAFL generates 8ps pulsewidth and 170 fs timing jitter when injection-pulse with 2-GHz peak-to-peak chirp.
