Abstract

A continuous wave laser beam of an infrared wavelength at 800 nm is used for two-photon excitation in a photobleaching polymer for 3D bits data storage. We successfully demonstrate the recording and reading of multiple layers of data bits up to a depth of 100 micrometers within a thick photobleaching polymer. The achievable 3D bit density may be up to 3.5 Tbits/cm³ if a variable tube length can be implemented into the recording and reading processes.
