1. A head mounted display system comprising:
an eyepiece comprising a waveguide stack, the waveguide stack comprising:
a first waveguide; and
a second waveguide; and
an image injection device configured to direct a multiplexed light stream into the waveguide stack, the multiplexed light stream comprising a plurality of light streams, wherein the plurality of light streams comprises a first stream of light having a different wavelength and a different polarization than a second stream of light,
wherein the first waveguide comprises wavelength and polarization selective first in-coupling optical elements, wherein the first in-coupling optical elements are configured to selectively in-couple the first stream of light while being transmissive to the second stream of light, and
wherein the second waveguide comprises second in-coupling optical elements configured to selectively in-couple the second stream of light while being transmissive to light having a same polarization as the first stream of light.
