We have developed a thermally tunable module to compensate polarization mode dispersion (PMD) and chromatic dispersion (CD) simultaneously. In this module, twins of linearly chirped fiber Bragg gratings (LCFBGs) are used to compensate PMD and one non-linearly chirped FBG (NLCFBG) is used to compensate CD in 40Gb/s optical fiber communication system. The fiber Bragg gratings are coated with uniform thin metal film, and by changing the applied current through the film, the tunable compensation for PMD and CD is achieved. The fabrications of the LCFBG and NLCFBG are both utilizing the linearly chirped phase mask, making the fiber Bragg gratings easy to obtain.
