Left: fringe peak at the ouptut of the correlator (y-axis, in linear scale). The red dashed line indicates the numerical correlation of the input signal. The green solid line shows the correlation of the signal through the optical correlator. Right: coherence envelope of the fringe signal (green dot), and envelope computed numerically (blue cross). The experimental envelope fits a Gaussian profile, which differs from the numerical computation only at the feet of the envelope. This could be imputed both to the experimental measurement uncertainties and to the estimation of the impulse response of the AWG.
