Abstract: This application provides an optical combiner and a related device for augmented reality. The optical combiner includes a transparent substrate and a metasurface layer. The metasurface layer is disposed on a surface of the transparent substrate. The metasurface layer includes a plurality of metasurface units arranged two-dimensionally. A spacing between two adjacent metasurface units in the plurality of metasurface units gradually changes along one or two dimensions, and a relative angle between any two adjacent metasurface units is not zero. The optical combiner can increase an ambient light transmittance and increase uniformity and a field of view of an image.

Abstract: The present invention discloses a mode multiplexer/demultiplexer and a switching node. The mode multiplexer/demultiplexer includes a multi-mode optical waveguide, a first transmission optical waveguide, and a second transmission optical waveguide. The multi-mode optical waveguide includes a first mode channel and a second mode channel. The first transmission optical waveguide includes a first coupling region that includes a first fundamental-mode channel, and the first fundamental-mode channel performs optical mode coupling with the first mode channel in the multi-mode optical waveguide. The second transmission optical waveguide includes a second coupling region that includes a second fundamental-mode channel, and the second fundamental-mode channel performs optical mode coupling with the second mode channel in the multi-mode optical waveguide. An effective refractive index of a fundamental-mode optical signal in the first coupling region is different from an effective refractive index of the same fundamental-mode optical signal in the second coupling region.
