Abstract
The multiplexing of holographic reflection gratings with a spatial frequency higher than 5400 lines/mm in photopolymerizable sol-gel materials is experimentally demonstrated. The effect of the angular separation of the gratings and exposure time is characterized. Moreover, 9 reflection gratings are angularly multiplexed with diffraction efficiencies between 6 and 12% using an energy of 9 mJ/cm2 in each exposure, resulting in a dynamic range M/# = 2.8.
