Abstract :
In this paper, 40-Gb/s all-optical 3R regeneration has been experimentally demonstrated based on semiconductor devices. The 3R regenerator incorporates an amplified feedback laser (AFL) for all-clock recovery and a semiconductor optical amplifier delayed interferometer as the optical decision gate. 40-GHz optical clock with low timing jitter and uniform amplitude is successfully recovered from the degraded signal by the AFL. The degraded signal is restored by the 3R regenerator with the Q-factor improved.
