Abstract

The all optical window equivalent-time sampling method based on symmetric Mach-Zehnder interferometer are present. A system model based on SOA dynamic model was founded to analyze sampling process. The pulse broadening in PIN and its response are discussed too. The evolution of sampling function due to control delay and width of control pulse are numerical calculated. Sampling error caused by ASE, noise of PIN and control pulse jitters are analyzed theoretically. This all-optical waveform sampling system with simultaneous submilliwatt optical signal sensitivity (20-dB signal-to-noise ratio) and subpicosecond temporal resolution is demonstrated. The results have shown that the SMZ sampler system combined with postprocess can monitor waveform with low error.
