Abstract
An optical device comprises a number of waveguides, e.g., color plates, that are individually formed to couple a corresponding color output of a micro-display engine and project an image into a human vision system. Some configurations include stacked structures for suppressing a predetermined wavelength range a corresponding to a wavelength range emitted from a waveguide. Techniques, devices, and systems disclosed herein can mitigate cross coupling that occurs between the waveguides to provide enhanced MTF values over devices that do not include the stacked structures. Individual optical devices configured to suppress a predetermined wavelength range are also provided.
