Abstract: Disclosed herein is a mixed illumination system including: a first light source; a second light source of different type than the first light source, where the wavelength an output of the second light source does not overlap with the wavelength of an output of the first light source; and a combiner which is configured to combine the output of the first light source and the second light source. The light from the first light source and the second light source are combined within the combiner into a combined beam.

Abstract: A wearable waveguide display having multiple input projection arrays configured to project an image into a waveguide via separate input couplers and project the image via an output element. The wearable display can be configured in a number of configurations that minimize weight and maximize comfort and resolution of the projected images. In some embodiments, the wearable waveguide display includes a first microLED array which outputs light into a first input coupler and a second microLED array which outputs light into a second input coupler. The first input coupler and the second input coupler both in couple light into total internal reflection in a waveguide. The incoupled light is outcoupled via an output optical element.

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.

Some embodiments of the methods and the apparatus include a waveguide based display including a waveguide including an in-coupling optical element and an out-coupling optical element, where the in-coupling optical element is configured to in-couple image containing light and the out-coupling optical element is configured to out-couple the image counting light towards a user, where the waveguide comprises an outer surface and an inner surface opposite to the outer surface, and wherein the inner surface is closer to the user than the outer surface; and a partially light blocking layer above the outer surface of the waveguide opposite to the user, where the partially light blocking layer is configured to keep eye glow light from entering the environment outside the outer surface of the waveguide.

Abstract: The present disclosure relates to modular waveguide displays including: a modular frame; a waveguide lens attached to the modular frame, where the waveguide lens in configured to be attached to the modular frame to locate one or more waveguides within the waveguide lens in front of the modular frame; and an optical engine which is configured to be attached to the modular frame, wherein, when the optical engine is attached to the modular frame, the optical engine is configured to provide image containing information to a front side of the one or more waveguides. Advantageously, a modular waveguide display allows for customization by a user. The modular waveguide display is designed to operate without such components as the optical engine when such functionality is undesired to save weight and power. Also, modular waveguide displays allow for parallel development of components such as the waveguide lens and the optical engine.

Abstract: Methods and apparatus for eye-glow suppression in waveguide systems is disclosed herein. Some embodiments of the methods and the apparatus include a source of image modulated light; a waveguide having an eye-facing surface and an external surface facing the outside world; an input coupler for coupling the light into a total reflection internal path in the waveguide; at least one grating for providing beam expansion and extracting light from the waveguide towards an eyebox; a polymer grating structure comprising a modulation depth and a grating pitch. The modulation depth is greater than the grating pitch across at least a portion of the polymer grating structure. Advantageously, the polymer grating structure is configured to diffract light entering the waveguide from the outside world or stray light generated within the waveguide away from optical paths that are refracted through the external surface into the outside world.
