Abstract: Alight beam shaping apparatus, a light beam shaping method, and a WSS are provided. The light beam shaping apparatus includes a port assembly and a first light beam shaping device, where the port assembly includes an input port. The first light beam shaping device is configured to perform phase adjustment on each input first light beam to adjust a beam waist width of each first light beam in a first direction and/or a beam waist width of each first light beam in a second direction, where the first direction is perpendicular to the second direction, and each first light beam comes from a corresponding input port.

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 electromagnetic wave control apparatus includes an upper electrode layer, a lower electrode layer, a liquid crystal layer, and a first metamaterial layer disposed between the upper electrode layer and the lower electrode layer. The first metamaterial layer includes a first array including alignment unit structures. A first surface of the alignment unit structure is a surface that is of the alignment unit structure and that faces away from the liquid crystal layer. A length-to-width ratio of the first surface of the alignment unit structure is greater than 1. A length of the first surface, a width of the first surface, and a spacing between two adjacent alignment unit structures range from 1 nm to 5000 nm.
