Paper Abstract

We propose a new tunable polarization-mode-dispersion compensator, which is substantially free from chromatic dispersion. The design uses a pair of high-birefringence linearly chirped fiber gratings. Each grating can adjust the differential group delay (DGD) nonlinearly by using a cantilever beam. The compensator can be tuned to operate over a range of wavelengths and can yield DGD values starting from 0 ps. Measured eye diagrams for a 10-Gbit/s system show that this compensator can greatly reduce the chromatic dispersion induced by a chirped grating.
