Abrégé

[Problem] To provide a wavelength selective polarization controller capable of controlling the polarization plane of optical wavelength multiplexing signals, for each wavelength component, and which does not generate time lag between each component. [Solution] This wavelength selective polarization controller has: a telecentric optical system (II) to which optical wavelength multiplexing signals are incident; a polarization controller (12) that controls the polarization plane of light output from the telecentric optical system; and an output optical system (13) for outputting to an optical path output from the polarization controller. The telecentric optical system (11) has: a first diffraction grating (15) to which the optical wavelength multiplexing signals are incident; and a first condenser (16) that condenses the optical wavelength multiplexing signals that have passed through the diffraction grating (15). The polarization controller (12) has a plurality of phase modulators (21, 22, 23).
