Recording of multiplexed volume gratings via a phase mask for augmented reality waveguides

This paper describes the experiment on multiplexing recording using a phase mask to create augmented reality waveguides. The study is distinguished by the application of photo-thermo-refractive glass as both holographic and substrate materials. The presented approach allows us to obtain the diffraction efficiency above 15% in each of the multiplexed gratings for sevenfold recording. The images output with the manufactured planar waveguide prototype are presented.
