Abstract: A method and apparatus for polarization measurements. A polarization state of an optical signal can be determined using a polarization analyzer comprising a polarization controller, a polarizer, a wavelength dispersive element and a photo-detector. The method and apparatus can be applied to polarization and polarization mode dispersion measurements in wavelength division multiplexed communication systems.
