We report on volume holographic recording at a blue-violet wavelength of 405 nm in a nanocomposite film dispersed with hyperbranched polymer nanoparticles possessing the ultrahigh refractive index. It is shown that the recorded nanocomposite film possesses the saturated refractive index modulation amplitude as high as 0.03. This result is promising for the realization of highly efficient holographic diffractive elements recorded in a panchromatic nanocomposite film.
