Polarization mode dispersion measurement method and polarization mode dispersion measurement system

摘要

PROBLEM TO BE SOLVED: To measure a smaller PMD value with a simple formation by a fixed analyzer method.;SOLUTION: Polarization mode dispersion larger than the polarization mode dispersion of a measuring object 1 is given by a reference object 23 to linear polarized light extracted by a first polarizer 22 from wideband light emitted from a wideband light source 21, and a plane of polarization of light to which the polarization mode dispersion is given is rotated by a rotor of the plane of polarization 24. A spectrum of linear polarized light extracted by a second polarizer 25 from light emitted from the other end side of the measuring object 1 is analyzed to fluid at least either of the maximum value and the minimum value of the polarization mode dispersion. The value based on the difference between the maximum value and the minimum value, or the difference between the maximum value and the value of the polarization mode dispersion of the reference object 23, or the difference between the minimum value and the value of the polarization mode dispersion of the reference object 23 is calculated as the value of the polarization mode dispersion of the measuring object 1.;COPYRIGHT: (C)2001,JPO
