Abstract
Systems and methods are provided for selectively incoupling light having different wavelengths into one of a plurality of waveguides. The systems and methods provided for selectively incoupling light having different wavelengths into one of a plurality of waveguides comprise a switching device comprising switchable reflective elements that can be configured to redirect incoming light towards an incoupling element associated with one of a plurality of waveguides.
