Abstract :
Compact optical clock recovery is demonstrated by utilizing filtered and amplified photocurrent in a traveling-wave electroabsorption modulator. The 40-GHz optical clock was recovered from a 40-Gb/s optical time-division multiplexed signal and transferred to a new clock wavelength. The recovered optical clock has 500-fs timing jitter and 8-ps pulsewidth.
