摘要： A wavelength selective switch includes a wavelength dispersive element that divides a beam input from an input port, a beam director that deflects a wavelength component, and a free space optical system that optically couple a input/output unit, the wavelength dispersive element, and the beam director. The free space optical system converts a shape of the beam such that a size extending in a second plane is relatively smaller than a size extending in a first plane, and to have a long axis and a short axis in a third plane. The long axis is inclined with respect to the first direction. The beam director includes a beam directing region in which a plurality of beam directing elements are arranged. The beam directing region deflects the respective wavelength components toward the predetermined output port. The beam directing region is provided to correspond to the shape of the beam.
