Analysis of Frequency Dependence of Output Stokes Parameters in an Optical Fiber System

In a non-depolarizing optical system, Mueller-Jones matrix can be used to describe the relation between the input Stokes vector and the output Stokes vector. However, even if the input light is quasi-monochromatic, the effect of depolarization should not be neglected in a practical optical fiber system. Mueller-Jones matrix should be modified to have the depolarizing effect included. The newly formulated equations are generalized for the input light with an arbitrary degree of polarization in an optical fiber system where the effect of depolarization is seriously considered.
