Abstract: Systems and methods for providing holographic waveguide display using integrated gratings in accordance with various embodiments of the invention are illustrated. One embodiment includes a waveguide display including a source of light, and a first waveguide including a grating structure including first and second gratings, and an input coupler configured to couple a first field-of-view portion of light, and couple a second field-of-view portion of light, wherein the first grating is configured to provide beam expansion in a first direction for the first field-of-view portion of light, and provide beam expansion in the first direction and beam extraction towards a viewer for the second field-of-view portion of light, the second grating is configured to provide beam expansion in a second direction for the second field-of-view portion of light, and provide beam expansion in the second direction and beam extraction towards a viewer for the first field-of-view portion of light.

Abstract: Disclosed herein are systems and methods for providing waveguide display devices utilizing overlapping integrated dual axis (IDA) waveguides. One embodiment includes a waveguide display device including: a first input image source providing first image light; a second input image source provide second image light; a first IDA waveguide; and a second IDA waveguide. The first IDA waveguide and the second IDA waveguide may include an overlapping region where a first two-dimensionally expanded first image light, a second two-dimensionally expanded first image light, a first two-dimensionally expanded second image light, and a second two-dimensionally expanded second image light is ejected towards an eyebox. Advantageously, resolution may be enhanced and field of view may be expanded through the use of overlapping IDA waveguides.
