1. A display system comprising:
an injection device configured to output a multiplexed light stream that includes a first light stream having at least one first light property and a second light stream having at least one second light property that is different from the at least one first light property, wherein the at least one first light property includes a first wavelength and the at least one second light property includes a second wavelength that is different from the first wavelength; and
a waveguide comprising one or more in-coupling optical elements that are arranged to receive at least a portion of the multiplexed light stream, wherein the one or more in-coupling optical elements are configured to selectively in-couple, into the waveguide, the first light stream having the first wavelength while being transmissive to the second light stream having the second wavelength, and wherein the one or more in-coupling optical elements comprise one or more Pancharatnam-Berry Phase Effect (PBPE) structures that are configured to selectively redirect, into the waveguide, incident light of the first wavelength independently of a polarization of the light.
