Abstract: An optical switching apparatus includes an input port, a dispersion component, a first filter, a redirection component, and output ports. The input port enables a first and a second beam to be incident onto the dispersion component, which decomposes the first and the second beams respectively into a plurality of first and second sub-beams, where the plurality of first sub-beams and second sub-beams belong to different bands. The first filter separates transmission directions of the plurality of first and second sub-beams into different transmission directions in a first direction (X) based on the different bands, enables the plurality of first and second sub-beams respectively to be incident onto a first area and a second area of the redirection component, where the first and second areas are separated in the first direction.

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: An optical system. A light source component generates a light beam. A light adjustment component adjusts a ratio of the S-polarized light and a ratio of the P-polarized light in the light beam. A first polarization beamsplitter mirror component splits a light beam adjusted by the light adjustment component into a first light beam and a second light beam, where the first light beam is a light beam of the S-polarized light, and the second light beam is a light beam of the P-polarized light. The first lens component projects the first light beam or a modulated first light beam to a first region. The second lens component projects the second light beam or a modulated second light beam to a second region.
