Abstract :
An 80 GHz electrical clock signal was successfully recovered from an 80 Gbit/s RZ optical data stream using direct optical injection locking of an 80 GHz InP/InGaAs HPT oscillator. The measured RMS jitter is less than 0.31 ps for 231-1 PRBS data signal. This is the first demonstration of the electrical clock extraction at such a high frequency using optical injection locking of an electrical oscillator.
