Abstract
The description relate to devices, such as augmented reality and/or virtual reality devices that employ optical waveguides. On example includes a first optical waveguide configured to receive light at an incidence angle and a second optical waveguide positioned in a non-parallel relation to the first optical waveguide. The second optical waveguide can be configured to receive the light through the first optical waveguide at a first location at the incidence angle, transmit the light within the second optical waveguide, and output the light from a second location back toward the first optical waveguide at the incidence angle.
