Abstract

In this paper we report on two-photon-excited bit by bit data storage within a photorefractive polymer composed of 53.9 weight percents of PVK (poly(N-vinylecarbazole)), 30wt% of DMNPAA (2,5-dimethyl-4-(p-nitrophenylazo)anisole), 16wt% of ECZ (N-ethylcarbazole) and 0.1 wt% of CdS quantum dots as a sensitizer. Multi-layer data sets with a layer spacing 20 mu are recorded using a pulsed ultrashort laser at a wavelength of 780 nm.
