An optical waveguide, for use a near-eye or heads-up display system, includes an input-coupler, an intermediate-component and an output-coupler. The input-coupler is configured to couple light corresponding to an image that is incident on the input-coupler, into the optical waveguide and towards the intermediate-component. The intermediate-component can be implemented as a Bragg polarization grating that comprises a stack of birefringent layers configured to diffract the light corresponding to the image that is incident thereon into a zero-order beam having one of right handed circular polarization or left handed circular polarization, and a first-order beam having the other one of right handed circular polarization or left handed circular polarization. The output-coupler is configured to couple, out of the optical waveguide, the light corresponding to the image that travels in the optical waveguide from the input-coupler to the output-coupler via the intermediate-component by way of total internal reflection (TIR).
