Chromatic dispersion monitoring is demonstrated for a 10 GHz train of 3 ps pulses at −45 dBm coupled average power and 100 ms sampling period by using a chirped quasi-phase-matched LiNbO3 waveguide with 625 GHz active bandwidth. The feasibility of monitoring 10 GHz, 24 ps pulses at −40 dBm power is verified by intensity autocorrelation measurements.
