Abstract
A wavelength selective switch and a wavelength selection method are provided. The wavelength selective switch comprises a plurality of input ports, via which a plurality of light beams are input respectively, each light beam including at least one optical signal of a predetermined wavelength; at least one output port; and a wavelength separation apparatus including a wavelength separation device and a micro-mirror group, the wavelength separation device being configured to separate at least one optical signal from a light beam input via a predetermined one of the plurality of input ports, and the micro-mirror group being configured to adjust a propagation direction of the at least one optical signal, so that the at least one optical signal is output via a predetermined one of the at least one output port.
