  • Publication number: 20210055551
    Abstract: A waveguide display includes a substrate transparent to visible light, a coupler configured to couple display light into the substrate as guided wave in the substrate, and a first VBG and a second VBG coupled to the substrate. The coupler includes a diffractive coupler, a refractive coupler, or a reflective coupler. The first VBG is configured to diffract, at a first region of the first VBG, the display light in the substrate to a first direction, and diffract, at two or more regions of the first VBG along the first direction, the display light from the first region to a second direction towards the second VBG. The second VBG is configured to couple the display light from each of the two or more regions of the first VBG out of the substrate at two or more regions of the second VBG along the second direction.

  • Publication number: 20210055553
    Abstract: A waveguide display includes a substrate transparent to visible light and a projector configured to generate display light for an image, where the display light includes display light for a first field of view (FOV) of the image and display light for a second FOV of the image. The waveguide display also includes a first input coupler configured to couple the display light for the first FOV into the substrate, a first set of gratings configured to couple the display light for the first FOV out of the substrate at a first two-dimensional array of locations of the substrate, a second input coupler configured to couple the display light for the second FOV into the substrate, and a second set of gratings configured to couple the display light for the second FOV out of the substrate at a second two-dimensional array of locations of the substrate.

  • Publication number: 20210055555
    Abstract: A waveguide display includes a waveguide and a grating coupler configured to couple display light into or out of the waveguide. The grating coupler includes at least a first grating layer and a second grating layer arranged in a stack. The first grating layer is characterized by a first thickness and includes a first transmission VBG configured to diffract display light of a first wavelength from a first field of view. The second grating layer is characterized by a second thickness greater than the first thickness and includes a second transmission VBG configured to diffract display light of the first wavelength from a second field of view greater than the first field of view.

  • Publication number: 20210055554
    Abstract: A waveguide display includes a waveguide transparent to visible light, a first volume Bragg grating (VBG) on the waveguide and characterized by a first refractive index modulation, and a second reflection VBG on the waveguide and including a plurality of regions characterized by different respective refractive index modulations. The first reflection VBG is configured to diffract display light in a first wavelength range and a first field of view (FOV) range such that the display light in the first wavelength range and the first FOV range propagates in the waveguide through total internal reflection to the plurality of regions of the second reflection VBG. The plurality of regions of the second reflection VBG are configured to diffract the display light in different respective wavelength ranges within the first wavelength range and the first FOV range.

  • Publication number: 20210055552
    Abstract: In a waveguide display, a first projector is configured to generate display light for a first field of view (FOV) of a display image. A first input coupler is configured to couple the display light for the first FOV into a visibly transparent substrate. A first set of gratings is configured to couple the display light for the first FOV out of the substrate at a first two-dimensional array of locations of the substrate. A second projector is configured to generate display light for a second FOV of the display image different from the first FOV. A second input coupler is configured to couple the display light for the second FOV into the substrate. A second set of gratings is configured to couple the display light for the second FOV out of the substrate at a second two-dimensional array of locations of the substrate.
