THE POLARIZATION DISPERSION OF STEP INDEX FIBER
阶跃光纤的偏振色散

Using the transverse shift and the cross time of the total reflected light,the polarization dispersion formula of the isotrope fiber are derived,in the cladding while counting in the cross time,the corrected formula of the polarization dispersion are derived.The change of polarization dispersion varying with the incident angle are calculated and analysed.
