Abstract :
A novel geometry for all-optical clock recovery using a semiconductor amplifier yields a strong locking mechanism in a short cavity. The recovered clock has a large locking bandwidth, low timing jitter, and fast lock-up time at a 2.5 GHz rate. Preliminary results at a 9 GHz rate also indicate a high quality recovered clock.
