Abstract :
We demonstrated 40 GHz all-optical clock recovery system using an erbium-doped fiber laser that incorporates a 10 GHz electro-absorption modulator and a linear optical amplifier. We successful recovered 40 GHz clock signals from a 40 Gb/s pseudo random bit sequences. Stable pulses with pulsewidth of 6 ps and timing jitter of 300 fs are obtained.
