Overview
abstract
We discuss the means for writing and reading information in a volume optical memory induced by two-photon processes. Photochromic materials based on reversible transformation of spiropyran molecules and polyacene photodimers have been used in 3D writing and reading with some success. The spectroscopic and physical properties of these materials are presented.
