Optical interconnections employing waveguides and total internal reflection holograms as a basic element are discussed. Methods of waveguide holography (WGH) allows the technology of VLSI systems to be matched with the optical interconnection conception. It is shown that WGH has an extremely high efficiency, it forms high resolution and wide view image, and it permits the signal-to-noise ratio to be increased.
