摘要： According to a WSS provided by embodiments of the present invention, without adding any additional component, other diffractive light different from +1-order diffractive light can be prevented from entering any input port or output port, provided that an LCOS panel is correspondingly rotated. This suppresses crosstalk with low costs.

摘要： Embodiments of the present invention disclose a wavelength selective switch WSS, including an input optical fiber collimation array, a first optical switching engine, a dispersion unit, an optical path converter, a second optical switching engine, a third optical switching engine, and an output optical fiber collimation array. A first beam is input from a first port of the input optical fiber collimation array. The first optical switching engine performs angle deflection on the first beam on a first plane. The dispersion unit demultiplexes, on a second plane, the angle-deflected first beam into multiple sub-wavelength beams. The second optical switching engine performs angle deflection on the multiple sub-wavelength beams that are obtained by means of demultiplexing. The dispersion unit multiplexes, on the second plane, the angle-deflected multiple sub-wavelength beams. The third optical switching engine performs angle deflection on the multiplexed multiple sub-wavelength beams on the first plane, so that the multiplexed multiple sub-wavelength beams are output from a second port of the output optical fiber collimation array. According to the foregoing technical solutions, optical switching in two dimensions is implemented, and input and output ports are arranged in two dimensions.

摘要： A wavelength selective switch includes: N input ports, an input-side fiber array, an input-side collimator array, an input-side beam deformation and polarization conversion component, an input-side wave-demultiplexing component, an input-side switching engine, a focusing transformation lens group, an output-side switching engine, an output-side wave-combining component, an output-side beam deformation and polarization conversion component, an output-side collimator array, an output-side fiber array, and M output ports. The focusing transformation lens group includes two identical aspheric convex lenses that are placed in parallel, where a curvature from a center to an edge of a surface of the aspheric convex lens changes continuously, and is used to control focal lengths of light with different wavelengths. A spatial position of the focusing transformation lens group and the curvature from the center to the edge of the surface are so set that light with different wavelengths from the input-side switching engine is focused to a corresponding position of the output-side switching engine respectively.

摘要： The present invention provides a node apparatus, where two N x N wavelength selective switches are used to form a parallel-connected structure, and two ends of each power splitter are separately connected to input ends of the N x N wavelength selective switches, and two ends of each power combiner are separately connected to output ends of the N x N wavelength selective switches, thereby transferring route switching selection work originally performed between multiple 1 x M wavelength selective switches to the inside of the N x N wavelength selective switch for implementation. Compared with an original structure using discrete components, the node apparatus is simplified, and when a traffic volume expands, the number of module slots on a line side does not need to be increased, thereby reducing usage costs eventually. The present invention is used for signal transmission in a node.
