Paper Abstract

A simple and low-cost all-optical equivalent-time sampling system is present. The optical sampling was realized by XGM in SOA and pulse-broadening in low-bandwidth PIN. A system model is funded based on noisy SOA dynamic function and a simplified equivalent electric circuit model about PIN. The sampling-recovery process had been simulated to validate the measuring capability of the sampler. Sampling error caused by ASE noise of SOA, thermal noise of PIN and time-domain jitter of control pulse is discussed too. Simulation results show that SOA XGM sampler can efficiently sample low repetition rate optical short pulse or short pulse with poor stability.
