Abstract
In this work, we report a novel method to mitigate the dependency of incident angle on diffraction efficiency by depositing a metal film on the grating structure. Moreover, the metallic structures strongly enhance the interaction between the incoming light and the nanostructures, leading to an improvement in diffraction efficiency. The results have shown the potential to overcome the bottleneck of augmented reality glasses, which require a large field of view with high efficiency.
