Abstract :
We report an experimental technique for accurate characterization of chromatic dispersion and its slope versus wavelength. The system consists of a fiber-based heterodyne Mach-Zehnder interferometer with a counter-propagating beam which is used to cancel the thermal phase noise. Three different silicon-based waveguides are characterized, obtaining a good agreement with theoretical simulations.
