ABSTRACT:
Methods for analyzing polarization mode dispersion of an optical device is provided. Various desired qualities of the device, including position dependent optical and physical qualities, can be determined. Experimental wavelength-dependent PMD data are provided that characterizes the entire optical device. The experimental data are Fourier transformed and an experimental Fourier transform is constructed. A theoretical Fourier transform is calculated and fit to the experimental transform by varying at least one parameter. Based on the fit parameters, one or more qualities, including a PMD profile of the device, can be determined. An apparatus for use with this method is also provided.
