Three-dimensional optical data recording and reading in polymer media with dyes

Investigations on 3D optical data recording in polymethylmethacrylate with spiropyran molecules by means of femtosecond Ti:Sapphire laser have been performed. The possibility for modification of polymer optical properties in volumes with sizes of 2 micrometers and recording time of < 1 ms has been demonstrated. A high image contrast of the recorded data allows to use amplitude methods of reading by both transmitted and reflected light, including parallel readout at a high speed.
