Abstract
A wavelength selective switchA includes a light input/output unit, a dispersive element, and a light deflection elementdisposed side by side on a predetermined axis C. The light input/output unithas a first portionin which light enters and exits a light input/output portby an optical axis inclined with respect to the predetermined axis C, and a second portionin which light enters and exits a light input/output portby an optical axis inclined with respect to the predetermined axis C. A light entry/exit angle of the light input/output portwith the predetermined axis C as a reference and a light entry/exit angle of the light input/output portwith the predetermined axis C as a reference differ from each other.
