1. An apparatus for routing selected wavelength bands in incoming light comprising:

  • an entry for receiving incoming light;

    a polarization-sensitive assembly positioned to separate the incoming light by polarization;

    one or more holographic assemblies containing multiplexed holograms for selectively reflecting the selected wavelength bands of the polarization-separated light; and

    an exit separate from the entry, where the polarization-sensitive assembly is also positioned to direct the reflected light to the exit.
