Digital Planar Holography

Digital Planar Holography (DPH) is a new technology, developed recently for fabricating miniature components for integrated optics. The essence of the DPH technology is embedding digital holograms, calculated in a computer, inside a planar waveguide. This allows for light propagation in the hologram plane rather than in the perpendicular direction and results in a long interaction path. Benefits of a long interaction path are well known for volume/thick holograms . On the other hand planar configuration provides easy access to the surface, where the hologram should be embedded.
