Abstract
In some embodiments, an optical device includes a waveguide having a first surface and a second surface opposing the first surface. The waveguide further includes an input coupler and an output coupler disposed over the first surface or the second surface. The optical device further includes a first prism disposed over at least the output coupler and over the first surface. The first prism is operable to increase a first projection angle of an image relative to a horizontal plane of the waveguide. The optical device further includes a second prism disposed under at least the output coupler and under the second surface. The second prism is operable to increase the second projection angle of light leakage relative to the horizontal plane of the waveguide.
