Abstract
A wavelength selective switch (WSS) apparatus. The WSS apparatus includes: a plurality of input/output port groups; a plurality of switching lens parts; a plurality of wedge prism parts; a beam expansion part; a wavelength dispersion part; a path combining part configured to combine the groups of the plurality of light beams transmitted from the switching lens parts on the dispersion axis; an imaging optic part; and a switching unit including a plurality of surface areas corresponding to the plurality of input/output port groups, the switching unit being configured to angular displace an angle of a selected wavelength on the switching axis such that the wavelength selected from multiple wavelength channels of an input port selected independently for each of the plurality of input/output port groups is transmitted to an output port of the plurality of input/output port groups selected independently.
