It is possible to implement a PMD generating function which can set a PMD vector for each wavelength over wide wavelength bands and which has a simple control algorithm. A PCD and a DR can be controlled independently because the PMD can be set for each wavelength. Input signal light 101 is input to a first birefringent crystal 104 through a first fiber collimator 102, and is output after a first PMD is added. This output light is input to the first Stokes mapping device 105, and is output after a state of polarization is variably controlled. This output light is input to a second birefringent crystal 106, and is output after a second PMD is added. This output light is input to a Second Stokes mapping device 107, and a state of polarization is variably controlled.
