Abstract
With the fluctuation of the environmental factors, such as temperature, wind, and atmospheric pressure, the birefringence of a fiber changes along the fiber link and the effects of polarization mode dispersion (PMD) are random and time-varying, which makes it necessary to design a tunable and adaptive Fiber communication; Optical fiber; Fiber Bragg grating; Differential group delay; Dispersion compensation; Polarization mode dispersion compensation; Birefringence; Linearly chirped fiber Bragg grating; Piezoelectric transducer PMD compensator. Such a novel tunable first-order PMD compensator has been proposed and characterized in this paper. The scheme of PMD compensation employs sampled fiber Bragg gratings fabricated with uniform-period phase masks. This all-fiber compensation technique is cost-effective and adjustable in designing the differential group delay (DGD) profile. The numerical simulation results show that the efficiency of this PMD compensator is assessed for 10 Gb/s NRZ transmission systems with large DGD. With the compensator, a significant improvement can be achieved in the bit rate pattern of the received signal.
