By using combined frequency and amplitude modulation of a cleaved-coupled-cavity semiconductor laser together with a phase-sensitive detection scheme, we have measured the chromatic dispersion in a single-mode silica fiber. The method presented can measure dispersion down to 0.03 psec/nm km and, with a slight modification to the measurement routine, also measure the total propagation time with a 10-7 accuracy.
