Effect of jitter on linear pulse-characterization techniques.
Linear pulse-characterization techniques based on electrically driven temporal modulators can measure the electric field of optical pulses with high sensitivity and accuracy. Synchronization of the electric-drive signal to the optical source under test is paramount to their implementation, and it is important to understand the impact of relative synchronization jitter on the measured experimental trace and on the reconstructed electric field. Derivations and simulations are presented for linear spectrography, spectral-shearing interferometry, and simplified chronocyclic tomography. For these three techniques, accurate characterization is obtained for relative jitter with a standard deviation as high as several times the pulse duration.
