STUDY OF THE RELATIONSHIP BETWEEN THE POLARIZATION AND THE PERTURBATION POWER SPECTRUM WITH MODE COUPLING IN A SINGLE-MODE FIBER
单模光纤中模耦合微扰功率谱与偏振关系的研究

The method to determine the mode-coupling coefficients by measuring the coupling ratio is proposed and the relationship between the birefringence and the perturbation power spectrum is obtained,from which the information about perturbation in the process of making fibers is given.So it is an effective method to develop polarized fibers.
