Fiber dispersion and propagation delay measurements with frequency and amplitude modulated cleaved coupled cavity semiconductor lasers.

By using combined frequency and amplitude modulation of a Cleaved Coupled Cavity (C(3)) 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 0.03ps/nm Km and, with a slight modification to the measurement routine, as o measure the total propagation time with a 10-(7) accuracy.
