An optical device comprises an optical waveguide including a volume of optically transparent material having a first longitudinal surface positioned opposite a second longitudinal surface across a width of the volume, a liquid crystal in-coupler, a controller to modulate a refractive index of the liquid crystal in-coupler, and an out-coupler. Light is in-coupled into the waveguide on a path that is dependent on the modulated refractive index of the liquid crystal in-coupler and is propagated along a length of the waveguide by total internal reflection between the longitudinal surfaces before being out-coupled by the out-coupler. In this way, light signals can be steered to create an image and/or to move an exit pupil of an image. WHUDs that employ such optical waveguides are also described."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems, devices, and methods for optical waveguides","description":"Systems, devices, and methods for optical waveguides that are well-suited for use in wearable heads-up displays (WHUDs) are described.
