Abstract:
Incorporation of silver ions into a dye-sensitized poly(vinyl alcohol)/acrylamide photopolymer is observed
to give better performance compared to other metal-ion-doped photopolymer holographic recording
media. Plane-wave transmission gratings were recorded in the photopolymer films using a He–Ne
laser, and various holographic parameters were optimized so as to explore maximum potential of the
material for various holographic applications. Silver-doped films showed good energy sensitivity,
and gratings recorded in optimized film exhibited a diffraction efficiency of more than 75%. The
potential of the material for holographic data storage applications is also studied using peristrophic
multiplexing
