Clock recovery from 160 Gbit/s data signals using phase-locked loop with interferometric optical switch based on semiconductor optical amplifier

Clock recovery from optical time division multiplexed data signals up to 160 Gbit/s is experimentally demonstrated using a phase-locked loop with a semiconductor optical amplifier in a loop mirror as a fast optical phase comparator. The timing jitter of the optical clock pulse extracted from a 160 Gbit/s data signal was <0.3 ps.
