Polarization mode dispersion measurement using phase-sensitive sideband detection

Image Number 3 for United States Patent #6362874.

A polarization mode dispersion (PMD) measuring arrangement utilizes a tapped-off portion of a signal that has experienced dispersion (such as, for example, propagating through a dispersive optical fiber). The measuring arrangement utilizes a phase-sensitive single sideband detection circuit in conjunction with a polarization beam splitter to generate magnitude and phase information for the lower and upper sidebands of each polarization of the received signal. The magnitude and phase information collected at a single frequency can be used to determine the polarization mode dispersion, eliminating the need to sweep the center frequency of the received optical signal to generate the PMD measurement.
