Original Abstract Submitted
an optical waveguide of the present disclosure has a first region and a second region, and the optical waveguide includes a waveguide dielectric layer, a grating layer and an encapsulation film layer laminated one on another. the grating layer includes a first grating and a second grating, the first grating is located in the first region, and the second grating is located in the second region. the waveguide dielectric layer is configured to transmit light rays coupled into the waveguide dielectric layer by the first grating to the second grating, to enable the light rays to be coupled out through the second grating. the encapsulation film layer covers a side of the first grating and the second grating away from the waveguide dielectric layer, and grooves of the first grating and the second grating are not filled with a material of the encapsulation film layer.
