Abstract: Provided is a wavelength selective switch where crosstalk is improved and miniaturization is realized. The wavelength selective switch includes: one or more input ports; one or more output ports; a polarization controller that adjusts a polarization state of light incident from the input ports; a dispersive element that demultiplexes wavelength-multiplexed light incident from the input ports; and a deflection element that controls deflection of the demultiplexed light. The dispersive element is a liquid crystal diffraction element having a liquid crystal alignment pattern where an orientation of an optical axis derived from a liquid crystal compound changes while continuously rotating in at least one in-plane direction.
