Abstract
The methods and systems used for storing and accessing information in three dimensions by means of two-photon absorption are described. The materials into which the information is stored are organic molecules dispersed in polymer matrices, which change structure and spectra after absorption of light. The writing and accessing of the information can be performed either bit-by-bit or in a two-dimensional (2-D) multibit plane format. Automated recording and readout three-dimensional (3-D) systems have been constructed and characterized. Channel error sources have been identified, and a custom spatial bit-error-rate test has been developed.
