摘要： PROBLEM TO BE SOLVED: To provide a variable polarization dispersion compensating device or variable polarization dispersion compensating method that can reduce loss of signal light and impart variable DGD with simple constitution.
SOLUTION: Polarization dispersion compensation is applied to signal light in a first polarized state which is input to a polarization maintaining fiber 114. During the polarization dispersion compensation, a polarization controller 115 brings light of frequency which is larger or smaller than the frequency of the signal light by the Brillouin shift frequency of the polarization maintaining fiber 114 into a second polarized state. The polarized wave in the second polarized state is input to the polarization maintaining fiber 114 through a polarization maintaining multiplexer 116 while holding the second polarized state so as to have an opposite direction from the signal light. The input polarized wave in the second polarized state is propagated in the polarization maintaining fiber 114 to generate induced Brillouin scattering in the maintaining fiber 114, thereby imparting different group refractive index variation to an X-polarized wave or Y-polarized wave of the signal light because of polarization dependency of the induced Brillouin scattering.
