Abstract: The embodiments of the present disclosure provide a method for manufacturing an optical waveguide and an optical waveguide, the method for manufacturing includes: providing a substrate; forming a first thin film layer, a second thin film layer and a sacrificial layer on the substrate in a stacked manner, a refractive index of the first thin film layer is larger than 2; exposing and developing the sacrificial layer so that the sacrificial layer forms a first mask layer; etching the second thin film layer by taking the first mask layer as mask so that the second thin film layer forms a second mask layer; removing the first mask layer, and etching the first thin film layer by taking the second mask layer as mask so that the first thin film layer forms a grating layer; and removing the second mask layer to form the optical waveguide comprising the grating layer and the substrate.
