Abstract: A color shifting illuminator includes a first luminescent material that absorbs first incident photons having an energy greater than or equal to a first threshold energy, and emits first photons with less energy than the first incident photons. The color shifting illuminator also includes a second luminescent material that absorbs second incident photons having an energy greater than or equal to a second threshold energy, and emits second photons with less energy than the second incident photons and less energy than the first photons. The first luminescent material and the second luminescent material are included in a waveguide, and the waveguide exhibits total internal reflection for the first photons and the second photons satisfying conditions for total internal reflection. An extraction region is coupled to the waveguide to emit the first photons and the second photons.
