The technology provides embodiments for a waveguide including gaps which turn the direction of light. Each of a plurality of planes (202a, 202b) located within a waveguide (123) includes a group of gaps (250) so that each of the gapped planes partially reflects out of the waveguide light within a first angle range and transmits down the waveguide light received within a second angle range. In some examples, the waveguide is formed by joining optically transparent sections, and each group of gaps is formed in a surface of each optically transparent section which becomes a joining surface when bonded with an abutting all flat surface of an adjacent section. The waveguide may be used in displays, and in particular in near-eye displays (NED)s. |
