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.
