Abstract :
Several channel degrading effects are present in non-static and dynamically-reconfigurable WDM systems and networks due to various types of dispersion in the optical transmission fiber. These effects must be addressed by tunable methods so that data signals do not fade with time. We demonstrate tunable compensation for chromatic dispersion accumulated in both single and multiple channels, and for polarization mode dispersion. We utilize a nonlinearly-chirped fiber Bragg grating that provides a dispersive function that can be varied continuously by tuning a single mechanical stretching element.
