Abstract
A method, a system and a computer program product configured to determine a differential group delay of two sequential optical beams based on a frequency dependence of a length of an optical path traveled by the two sequential optical beams in a dispersion compensation grating. The determined differential group delay provides a measure of polarization mode dispersion in the dispersion compensation grating.
