Memory and devices for fast nondestructive optical processing [25] in this case, the ground state (br) and the complex m state are usually used as the two binary states, that is, 0 and 1, respectively. A novel three-dimensional (3-d) optical memory device is presented that allows fast random access of the information and extremely high bit densities. We present here an experiment of optical information storage of bacteriorhodopsin (br) polymer film made from variant m1b a recording system of three-wavelength has been set up in the experiment. The complication of 3-d storage within the use of parallel architectures enhances the speed of such memories t he p intermediate then relaxes since the laser array can activate molecules in various places throughout the chosen illuminated page.

Doğan a timuçin and john d downie, phenomenological theory of photochromic media: optical data storage and processing with bacteriorhodopsin films, journal of the optical society of america a, 14, 12, (3285), (1997. The possibility of layer-by-layer reading of information in photoreversible medium based on bacteriorhodopsin is considered we propose to use for information reading the light with wavelength in the absorption spectrum of k- intermediate, which is shifted relative to the absorption spectra of b- and m-intermediates into the long wavelength region. The br based 3-d optical storage system discussed above is only one of the many possible architectures other forms of br polymer matrix such as a br cube oriented in-various polymer matrices by electrical fields can also be used in a 3-d optical storage system. 3-d optical data storage technology abstract 3d optical data storage is the term given to any form of optical data storage in which information can be recorded and/or read with three dimensional resolution (as opposed to the two dimensional resolution afforded, for example, by cd.

Among the most promising of the new alternatives are photopolymer-based devices, holographic optical memory storage devices, and protein-based optical memory storage using rhodopsin, photosynthetic reaction centers, cytochrome c, photosystems i and ii, phycobiliproteins, and phytochrome.

The optical storage media used in the 3-d memory zyxwvutsr currently under development at syracuse university is a diam in 2-d in 3-d (3d/2d) bit polymer based, homogeneous hydro-gel encapsulating (wm 1 disk cube (10-sm) bacteriorhodopsin and sealed into an optical cuvette [9.

We contend that three-dimensional optical memory devices made from bacteriorhodopsin utilizing the two photon read and write-method is such a technology with which the future of memory lies in a prototype memory system, bacteriorhodopsin stores data in a 3-d matrix. 3d optical data storage is related to (and competes with) holographic data storage traditional examples of holographic storage do not address in the third dimension, and are therefore not strictly 3d, but more recently 3d holographic storage has been realized by the use of microholograms. Title = efficient algorithms for computing with protein-based volumetric memory processors, abstract = with an ever increasing volume of digital data there is a huge increase in the demand for much faster, smaller, and denser storage technologies.

3-d optical memories using protein bacteriorhodopsin molecular electronics is an emerging field in the development of data storage devices memory is needed for recording information for future processing and references. List of figures fig 1 3-d optical memory information storage and retrieval 4 fig 2 influence of nonlinearity on the waist size of a gaussian beam. The optical film described above forms a two-dimensional (2-d) storage device however, the invention can be extended to a three-dimensional (3-d) layer or block of material, since br can be oriented and embedded in a variety of host materials. How has bacteriorhodopsin development been progressing over the last year the protein is definitely proving itself worthy of serious consideration for use in miniaturized, three dimensional optical memory devices and systems, but realization of commercial 3-d holographic memories is still about three years away.

3 d optical memory storage in bacteriorhodopsin

Bacteriorhodopsin-based 3d optical memory protein is being developed as a three dimensional optical storage memory [3] [4] volumetric optical memory based on bacteriorhodopsin. In a prototype memory system, bacteriorhodopsin stores data in a 3-d matrix the matrix can be build by placing the protein into a cuvette (a transparent vessel) department of computer engineering. We experimentally and theoretically investigated the optical switching characteristics of bacteriorhodopsin (br) at λ=633 nm using the pump-probe method a diode-pumped second harmonic yag laser (λ=532 nm which is located around the maximum initial br state absorption) was used as a pumping beam and a cw he-ne laser (λ=633 nm which is around the peaks of k and o states) was used as a probe.

The photoactive protein, bacteriorhodopsin (br), may be used as the recording medium in optical three-dimensional memories experiments with a sequential, one-photon read/write scheme have shown promising results. Films of bacteriorhodopsin for use in optical memories with reproducibility of optical quality and performance, and to verify performance by incorporating these films in two ambient temperature optical memory prototypes.

Figure 65: schematic diagram of a fourier transform holographic (fth) associative memory with read/write fth reference planes using thin polymer films of bacteriorhodopsin to provide real-time storage of the holograms note that a partial input image can select and regenerate the entire associated image stored on the reference hologram. 3-d optical memory storage in bacteriorhodopsin abstract with the growth of information over last few decades, demands for its efficient storage and faster processing has reached new dimensions.
