We describe briefly, the mechanism and characteristics of a versatile new photochromic molecule that is capable of performing as a medium for non-destructible high capacity readout molecular storage devices. This molecular memory consists of two different molecular components, chemically bonded together. It retains the photochromic and spectroscopic properties of each individual molecular component...
A novel method for accessing information from two-photon 3D volume memory devices is presented. We have used the decrease in laser intensity induced by two-photon absorption as the means for reading 3D information. The ratio of the initial laser intensity to the intensity after two-photon absorption is increased drastically by passing both beams through a second and fourth harmonic crystal. This...
