Bragg Multiplex Holograms Integrated with Planar Waveguides
Significant progress in high-resolution phase holographic materials such as dichromated gelatin (DCG), PVA-based polymers, PMMA-based polymers, and DCG/ polymer grafts, has stimulated several attractive applications of high-efficiency Bragg holography, including holographic notch filters, Lippmann holographic mirrors and holographic optical elements (HOEs), display holograms, holographic gratings, solar-control holowindows, and, recently, VLSI Holoplanar™ interconnects (based on Bragg multiplex holograms, integrated with planar waveguides1), developed in POC's optics lab.
