摘要： A memory device includes a bit cell including an adjustable transmittance component having a first side and a second side. The adjustable transmittance component has an adjustable transmittance state representative of a bit value of the bit cell. The memory device further includes a photon detector optically coupled to a second side of the adjustable transmittance component. A technique related to the memory device includes determining a transmittance state of the adjustable transmittance component and providing a bit value for the bit cell based on the transmittance state. Another technique related to the memory device includes determining a bit value to be stored at the bit cell and configuring the adjustable transmittance component to have a transmittance state corresponding to the bit value.

摘要： For amplifying the photosensitivity of a ferroelectric crystal in which information is to be stored, an external field applied to the crystal is created by means of a heavily doped, reduced photocell crystal illuminated uniformly by radiation within the absorption band of the crystal. The photocell crystal connected to the terminals of the lightly doped, non-reduced ferroelectric crystal, of which the resistivity is very much higher than that of the photocell crystal, develops a very high voltage which relaxes with a high time constant. Such a voltage increases the variations in the birefraction of the ferroelectric crystal.

摘要： Holographic apparatus utilizes a multiphoton process for writing and single photon for reading. Dependence upon a virtual first photon absorption rather than an actual absorption for the information-containing radiation with reading accomplished at the same energy avoids unwanted erasure during readout while preserving the versatility of optical erasure (by multiphoton absorption). In a preferred embodiment, the apparatus is adapted for recording of multiple images superimposed within a threedimensional medium. Typical media are ferroelectric with information storage taking the form of local changes in refractive index due to a corresponding change in electronic configuration.

摘要： A holographic storage media (10) is fabricated from a thin layer of photopolymer recording media. The photopolymer recording media is disposed between a substrate (48) and a capping layer (56). The media (10) is divided into a plurality of storage regions (54), which are formed within wells (52) to isolate each of the regions (54). During a record operation, a pumping operation is first performed to remove oxygen molecules from the media by bombarding the select region that is to have an interference pattern recorded therein with photons for a predetermined duration of time. Once the oxygen molecules have been depleted, then a data beam is generated with data superimposed thereon and a reference beam generated for interference with the data beam in the storage region (54). This results in the recording of an interference pattern.

摘要： A new type of holographic recording in photorefractive crystals is disclosed, termed orthogonal data storage, in which counterpropagating, reflection mode holograms are wavelength multiplexed to form gratings lying along a common axis. It is shown that this configuration provides substantial improvements in data storage capacity in comparison to prior art systems and that higher coupling coefficients are achieved. In consequence, not only storage of data but a wide range of other devices including wavelength selective filters, lenses and optical correlation systems are disclosed. Further, methods of writing and processing metastable images are disclosed which substantially improve the strength of the gratings that are permanently developed in the medium. These methods include advantageous use of electrical potentials and photovoltaic properties, together with different interrelationships during processing.

摘要： The present invention, in order to increase the optical efficiency of holograms recorded in the body of a photosensitive electro-optical material in the form of a refractive index grating, exploits the existance, under special conditions of operation of ferro-electric materials, of non-linear relationships between the double refraction and the electric field. To this end, electric fields of different value are applied to the ferro-electric material during the recording and read-out phases. The invention applies to large capacity optical stores and also has applications in coherent optical systems employing holographic lenses.
