Title: WAVELENGTH MULTIPLEXING IN WAVEGUIDES
Abstract:
A stacked waveguide assembly can have multiple waveguide stacks..Bach waveguide stack can include a plurality of waveguides, where a first waveguide stack may be associated with a first subcolor of each -of three different colors, and a second waveguide stack may be associated with a second subcolor of each of the three different colors. For example, the first stack of waveguides can incouple blue, green, and red light at 440 tun, 520 am, and 650 -nm, respectively. The -second stack of waveguides can incouple- blue, green, and red light at 450 nm, 530 nm, and 660 nm, respectively.
