Abstract
Aspects described herein generally relate to a waveguide and/or an associated display apparatus. The waveguide includes a plurality of optical input ports configured to receive optical light, at least one optical output port configured to output at least a modified portion of the optical light, and a plurality of transmission channels, each coupled to one of the plurality of optical input ports and configured to transmit the optical light from a respective optical input port to the at least one optical output port. The plurality of transmission channels are arranged to cause the optical light diffracted from at least a first one of the plurality of transmission channels to partially overlap, at the at least one optical output port, with the optical light diffracted from at least a second one of the plurality of transmission channels.
