Diffraction Efficiency Enhanced Volume Holographic Gratings via Coupling Ag Thin Film

Diffraction Efficiency Enhanced Volume Holographic Gratings via Coupling Ag Thin Film

Volume holographic gratings (VHGs) act as an in-coupler or out-coupler could be applied in holographic waveguide display system in which high diffraction efficiency is one of the key factors. Here, VHGs coupled with Ag thin film to enhance its diffraction efficiency is demonstrated. The first-order...
