Abstract

Transmission volume holograms recorded in two types of methacrylate-based photopolymer films that include benzyl n-butyl phthalate (BBP) or Poly(methyl methacrylate) (PMMA) are studied. It is shown that both BBP and PMMA molecules can be uniformly dispersed into methacrylate monomers and that a refractive index modulation as high as ∼0.005 is recorded by optimizing their volume concentrations. Moreover, it is also shown that the additional doping of silica nanoparticles substantially suppresses polymerization shrinkage without increasing optical scattering loss.
