Abstract: Embodiments of the disclosure provided herein include waveguide combiners. More specifically, embodiments described herein provide for waveguide combiners with a waveguide layer and a coating having a tapered portion disposed thereover. The waveguide includes one or more gratings, the one or more gratings including a plurality of grating structures disposed over a waveguide substrate, wherein the grating structures include a waveguide material, and the plurality of grating structures include exterior grating structures at outer edges of the one or more gratings. A waveguide layer is disposed over the waveguide substrate between the exterior grating structures and an edge of the waveguide substrate, the waveguide layer including the waveguide material, and a coating disposed over the waveguide layer, the coating having a tapered portion that is tapered from at least one of the exterior grating structures to a planar portion of the coating.

Abstract: The present disclosure relates to augmented reality devices and related methods. In one or more embodiments, an augmented reality device includes a projection system and a waveguide. The projection system includes a projector and a prism. The projector projects an image along the projectors major axis. The prism refracts the image having a first spectrum, a second spectrum, and a third spectrum. The waveguide is disposed at a wrap angle from a plane formed from the major axis of the projector. The waveguide includes an input coupler and an output coupler. The input coupler includes input structures at an input period and an input orientation and the input coupler is configured to receive the spectrums at different corresponding input angles. The output coupler includes output structures at an output period and an output orientation and the output coupler out couples the respective spectrums at an about equal output angle.

Abstract: Certain aspects of the present disclosure include an optical device. The optical device generally includes an in-coupler (IC) configured to receive light from a projector, where the IC includes at least one grating line offset (GLO) associated with one or more phase deviations of the light from the projector. The device also includes a waveguide and an output coupler (OC), where the IC is configured to redirect the light from the projector to the OC through the waveguide.

Abstract: Single-sheet waveguide combiners having increased field-of-view for multiple colors by enabling separate action on different colors without creating spurious paths are provided. A waveguide includes a first region including an in-coupler (IC) grating for a first color; a second region including an IC grating for a second color and a third color; a third region including an out-coupler (OC) grating for the first color and an eye-pupil-expander (EPE) grating for the second color and the third color; a fourth region including an EPE grating for the first color; and a fifth region including an OC grating for the second color and the third color and an EPE grating for the first color, wherein the fifth region at least partially overlaps with the third region.
