Abstract: A wavelength switching apparatus includes M input components, a first optical component, a first switch array, a second switch array, a second optical component, and K output components. The M input components include at least one local input component having N input ports, and a light beam input by the local input component can be converged, under an action of the first optical component, on a row of switch units that are in the first switch array and that are corresponding to the local input component. In this way, this is equivalent to further connecting an N*1-dimensional WSS to an input end of an M*K-dimensional WSS, so that the wavelength switching apparatus can integrate a wavelength adding function based on the M*K-dimensional WSS.

Abstract: The present disclosure provides example wavelength selective switch (WSS), wavefront control element, and integrated liquid crystal on silicon (LCoS). One example WSS includes an input port fiber array, a demultiplexing/multiplexing grating group, an output port fiber array, and a beam deflection component group including two beam deflection components and at least one wavefront control element located between the demultiplexing/multiplexing grating group and the beam deflection component group or integrated with the LCoS. At least one beam deflection component is a LCoS. The input port fiber array receives multi-wavelength optical signals. The demultiplexing/multiplexing grating group demultiplexes and outputs the multi-wavelength optical signals. The beam deflection component group deflects the multi-wavelength optical signals to the demultiplexing/multiplexing grating group. The demultiplexing/multiplexing grating group multiplexes the multi-wavelength optical signals to the output port fiber array. The wavefront control element and the LCoS jointly modulate optical signals transmitted through N*M wavelength channels.

Abstract: An electrical switching cluster system includes a plurality of input nodes, a plurality of intermediate nodes, and a plurality of output nodes. Each of the input nodes performs electrical switching on electrical signals to obtain a plurality of groups of first electrical signals, and converts one group of first electrical signals into a multi-wavelength first optical signal. Each of the intermediate nodes demultiplexes a plurality of first optical signals to obtain a plurality of groups of second optical signals, and multiplexes optical signals of different wavelengths in the plurality of groups of second optical signals to obtain a plurality of multi-wavelength third optical signals. Each of the output nodes converts one third optical signal into one group of second electrical signals, and performs electrical switching on a plurality of groups of second electrical signals to output the plurality of groups of second electrical signals through any output port.
