Abstract:
An optical waveguide, which includes a medium layer and N semi-transmissive, semi-reflective films supported by the medium layer. The semi-transmissive, semi-reflective films are arranged in sequence along a first direction perpendicular to a thickness direction of the medium layer. The orthographic projections of two adjacent semi-transmissive, semi-reflective films on a plane parallel to the thickness direction of the medium layer have an overlap region. A contour of each semi-transmissive, semi-reflective film is a curved surface structure, curved surface structures of the N semi-transmissive, semi-reflective films are N continuous sub-curved surfaces formed by segmenting a same curved surface respectively, a sum of heights of the N sub-curved surfaces is a height of the curved surface, and a concave side of the curved surface structure of each semi-transmissive, semi-reflective film faces towards a same bottom surface of the medium layer.

Claim (Index 12):
A method for manufacturing an optical waveguide, comprising:\n forming a plurality of sub-medium layers, each of the sub-medium layers having at least one splicing surface, each splicing surface being a concave surface or a convex surface, and splicing the plurality of sub-medium layers together via each splicing surface so as to form a medium layer, wherein the method further comprises: prior to splicing the plurality of sub-medium layers together, forming, on at least one of two splicing surfaces of two adjacent sub-medium layers to be spliced in the plurality of sub-medium layers, a semi-transmissive, semi-reflective film that covers the splicing surface, so as to form a plurality of semi-transmissive, semi-reflective films arranged in sequence, each semi-transmissive, semi-reflective film being sandwiched between two splicing surfaces of two adjacent sub-medium layers, wherein a contour of each of the semi-transmissive, semi-reflective films follows a curved surface structure, and wherein if the semi-reflective films are arranged in sequence such that the contour of each is continuous with the next forming a continuous, larger curved surface, a sum of heights of the plurality of sub-curved surfaces is a height of the curved surface, and a concave side of the curved surface of each of the semi-transmissive, semi-reflective films faces towards a same bottom surface of the medium layer.
