Abstract
The invention relates generally to optical data storage media, and more specifically, to holographic storage media. In one embodiment, an optical storage medium composition includes a polymer matrix. Disposed within the polymer matrix is a reactant capable of undergoing a modification that alters the refractive index of the composition upon receiving an energy transfer from an excited sensitizer. A non-linear sensitizer is also disposed within the polymer matrix, and the sensitizer includes a metal-substituted subphthalocyanine (M-sub-PC) reverse saturable absorber configured to become excited upon exposure to light beyond an intensity threshold at approximately 405 nm and configured to transfer energy to the reactant.
