Abstract
We present a scheme for recovering a 10-GHz clock from a 40- and 80-Gb/s time-division-multiplexed (TDM) return-to-zero (RZ) data stream. The proposed clock recovery is successfully demonstrated using an electrical phase-locked loop (PLL). The jitter of the recovered clock is estimated to be around 50 fs. The key part in the proposed clock recovery circuit is a LiNbO3 Mach-Zehnder modulator, which is shown to be highly effective in optical to electrical down conversion.
