Random polarization coupling with a broadband source in birefringent polarization-maintaining fibers is carefully studied. The effect of the broad bandwidth of light on cross talk is formulated in the mode-coupling parameter by means of the autocorrelation function of the light electric field. It is shown that, for light with a Lorentzian-shaped spectrum, cross talk increases as the spectral width becomes larger but is invariant for light with a Gaussian- shaped spectrum.
