Abstract: Typical waveguides rely on total internal reflection between the outer surfaces of substrates, which can make them highly susceptible to beam misalignment caused by nonplanarity of the substrates. In the manufacturing of the glass sheets commonly used for substrates, ripples can occur during the stretching and drawing of glass as it emerges from a furnace. Although glass manufacturers try to minimize ripples using predictions from mathematical models, it is difficult to totally eradicate the problem from the glass manufacturing process. Typically, these beam misalignments manifest themselves as image distortions and non-uniformities in the output illumination from the waveguide. Many embodiments of the invention are directed toward optically efficient, low cost solutions to the problem of controlling output image quality in waveguides manufactured using commercially available substrate glass and to the problem of compensating the image distortions and non-uniformity of curved waveguides.

Abstract: Disclosed herein are systems and methods for providing waveguide display devices utilizing overlapping integrated dual action (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.

Abstract: A waveguide display comprises: a waveguide supporting a single grating layer; a source of data-modulated light; a first input coupler for directing a first spectral band of light from the source into a first waveguide pupil; a second input coupler for directing a second spectral band of light from the source into a second waveguide pupil; an output coupler comprising multiplexed first and second gratings, at least one fold grating for directing the first spectral band along a first path from the first pupil to the output coupler and providing a first beam expansion; at least one fold grating for directing the second spectral band along a second path from the second pupil to the output coupler and providing a first beam expansion. The first multiplexed grating directing the first spectral band out of the waveguide in a first direction with beam expansion orthogonal to the first beam expansion. The second multiplexed grating directing the second spectral band out of the waveguide in the first direction with beam expansion orthogonal to the first beam expansion.

Abstract: Systems for the manufacturing of waveguide cells in accordance with various embodiments can be configured and implemented in many different ways. In many embodiments, various deposition mechanisms are used to deposit layer(s) of optical recording material onto a transparent substrate. A second transparent substrate can be provided, and the three layers can be laminated to form a waveguide cell. Suitable optical recording material can vary widely depending on the given application. In some embodiments, the optical recording material deposited has a similar composition throughout the layer. In a number of embodiments, the optical recording material spatially varies in composition, allowing for the formation of optical elements with varying characteristics. Regardless of the composition of the optical recording material, any method of placing or depositing the optical recording material onto a substrate can be utilized.
