A novel three-dimensional (3-D) optical memory device is presented that allows fast random access of the information and extremely high bit densities. This device is based on two-photon writing, reading, and erasing of the information in a photochromic material embedded in a polymer matrix. Absorption and emission data show that two-photon writing and reading of information is feasible. The advantages and properties of such a 3-D optical memory are discussed.

Analyses of bit-oriented optical memories using photochromic media.
TLDR
To be able to erase at the same rate as data are written, the erase source must have a power output as much as an order of magnitude greater than that of the write source, and this may present a serious problem.
