Abstract
A wavelength selective switch includes an input/output unit that has a first port group including a first input port and a first output port and a second port group including a second input port and a second output port; a wavelength dispersion element that disperses wavelength multiplexing light in wavelength components; a deflection element that deflects a direction of an incident beam; and an optical system that optically couples the input/output unit, the wavelength dispersion element, and the deflection element along a predetermined axis. The optical system includes an optical component, a first input beam input from the first input port is inclined at a first angle to the predetermined axis and is incident on the optical component, and a second input beam input from the second input port is inclined at a second angle to the predetermined axis and is incident on the optical component.
