Projection display with electrically controlled waveguide-routing

A display device including:

• a solid material for conveying optical energy;
• at least a first electrically-conductive material forming a first electrode, said first electrode confronting said solid material;
• an optical frequency source means including an optical exciter of a first frequency and a frequency doubler means coupled to be excited by said optical exciter;
• at least one pixel waveguide segment traversing said solid material along a plane of said solid dielectric material;
• a plurality of output waveguide segments traversing said solid material along said plane, said output waveguide segments abutting said pixel waveguide segment at a plurality of intersections;
• a plurality of electrically-controlled optical redirectors, each optical redirector being disposed transverse of one of said intersections, said optical redirectors to reflect optical energy from said pixel waveguide segment into said output waveguide segments;
• and
• an optical collection element coupled to receive optical energy projected out of said plane for focusing said optical energy at a remote projection surface.
