Abstract: 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).

Abstract: A MEMS laser scanner is disclosed for use in a near-eye display including an increased field of view (FOV). In embodiments, one or more polarization gratings may be applied to the mirror of the MEMS laser scanner, which polarization gratings may be configured according to the Bragg regime. Using light of different polarizations, the MEMS laser scanner is able to expand the FOV without increasing the range over which the mirror of the scanner oscillates.
