Polarized wave mode dispersed compensator, application to polarized wave mode dispersed compensating method and its optical communication system

摘要

In order the compensating section and the description above in order to compensate the polarized wave mode dispersion which the optical transmission line the polarized light includes the group delay time difference grant section which grants group delay time difference to the light which is converted due to the 1st polarized wave controller and the aforementioned 1st polarized wave controller which administer polarized light conversion to the light which is spread is granted to the aforementioned light with propagation process of the aforementioned optical transmission line in the light which is compensated, for the polarized light state to become one linearly polarized light, the light where polarized light conversion is administered by the 2nd polarized wave controller and the aforementioned 2nd polarized wave controller which administer polarized light conversion, the description above oneIn order the polarized light separated section and the description above which are separated into the other linearly polarized light which crosses in the linearly polarized light and this one linearly polarized light the optical strength test section and the description above which measure the strength of the other linearly polarized light which is separated to minimize the strength of the other linearly polarized light which was measured, the polarized wave mode dispersed compensator which features that it has the aforementioned compensating section and the control section which controls the aforementioned 2nd polarized wave controller.
