Abstract
A novel technique to introduce tunable linear chirp to a uniform fiber Bragg grating (FBG) without shift of central Bragg wavelength based on a magnetic field applied to a magnetostrictive rod capable of tuning polarization mode dispersion (PMD) is proposed. This all-fiber PMD compensation technique is cost-effective and flexible in designing the differential group delay (DGD). Based on the numerical simulations, a 10 Gb/s NRZ transmission system is compensated by this grating. The result demonstrates a significant improvement can be achieved in the eye pattern of the received signal.
