160 Gbit/s Clock Recovery Using Electroabsorption Modulator-Based Phase-Locked Loop

Clock Recovery from 160 Gbit/s optical time-division-multiplexed data stream is experimentally demonstrated using an electroabsorption modulator-based phase-locked loop. The recovered clock signal exhibits excellent stability, with a rms timing jitter of 230 fs, a dynamic range of 25 dB, and a hold range of + - 8 MHz.
