In this paper, we present a scheme for extracting a 10GHz clock from the 80Gb/s optical time division multiplexed (OTDM) return to zero (RZ) data stream. The proposed clock recovery is based on the offset locking technique. By using the input data composed of a repeating "101" pattern, residue jitter free operation for clock recovery is demonstrated. The method utilizes a LiNbO3 Mach-Zehnder (MZ) intensity modulator for cross-correlation detections.
