Method of compensating the chromatic dispersion and the polarization mode dispersion of an optical fiber system

摘要

A dispersion compensating chirped optical fiber Bragg grating (11) according to our invention is formed in polarization maintaining (PM) fiber (32) having birefringence of at least 10-6, preferably 10-5 or more. Use of the PM fiber makes possible substantial cancellation of the polarization mode dispersion that typically is unavoidably present in chirped Bragg gratings for dispersion compensation.
