Paper Abstract

A potential application of the novel 4, 4'-bis(diphenylamino-trans-styryl)-biphenyl (BPSBP) for three-dimensional optical data storage by two-photon induced photobleaching was investigated. The fluorescence of BPSBP molecules under two-photon absorption excited by a focused femtosecond(fs) pulsed laser was quenched; therefore, bit data can be recorded by two-photon bleaching in a BPSBP doped Polymethylmethacrylate (PMMA) film and be read nondestructively as darker spots than the non bleaching area emitting fluorescence under low power fs pulsed laser illumination. This enables three-dimensional data recording and reading using a two-photon scanning fluorescence microscope. Experimental results of recording and reading in three layers of three-dimensional data bits with a transverse bit separation of 5μm and an axial layer separation of 8μm (0.5x1010bits/cm3) were presented, and 107 readout cycles were achieved possibly.
