73‐3: High Refractive Index Photopolymer Fabricated Holographic Grating used for RGB Waveguide‐type Display

Abstract

Using high refractive index photopolymer to fabricate the full color holographic coupled grating for a waveguide-type display system was designed. With the optimized high refractive index photopolymer, we have the possibility to find the optimized design for stacking red, green, blue (RGB) three layers coupled-gratings together and propagating RGB wavelength in one layer waveguide without crosstalk. The proposed method and system was confirmed experimentally.
