Abstract: An improved linear light modulator array is formed with opposing electrodes which extend away from the optic surfaces of optoelectronic material used to form the array. A uniform electric field is created across a modulator volume, generally perpendicular to light propagation within the modulator volume. The modulator volume of an element in the array is a function of electrode length, width and separation. Additional elements are defined by additional pairs of electrodes. Trenches in the electrooptical material separate adjacent electrodes of separate modulator elements. A preferred depth of trench penetrates the electrooptical material about 10-15% of the distance between opposing electrodes. The geometry is obtained by cutting optoelectronic material into strips. Cut sides of the strips are metallized, one at a time, with the opposite side temporarily affixed to a carrier.

Abstract: An improved linear light modulator array is formed with opposing electrodes which extend away from the optic surfaces of optoelcctronic material used to form the array. A uniform electric field is created across a modulator volume, generally perpendicular to light propagation within the modulator volume. The modulator volume of an element in the array is a function of electrode length, width and separation. Additional elements are defined by additional pairs of electrodes. The geometry is obtained by cutting optoelectronic material into strips. Cut sides of the strips are metallized, one at a time, with the opposite side temporarily affixed to a carrier. Aligned trenches are cut in the metallized strips to separate electrode pairs and define array elements.

Abstract: Any of inorganic and bio-organic substances and molecules, and beads, pucks and like small things, that are both (i) electrically charged to a first polarity, and (ii) immersed in a fluid transport medium within (iii) an electrochemical cell, are assembled and patterned by action of moving these inorganic and bio-organic substances and molecules, etc. to a patterned electrode having an opposite, second, polarity under force of an applied electric field. The electrode patterned with conductive areas may be further, separately, patterned with chemicals, for example agarose gel, that chemically accept or reject the substances and molecules, etc., especially as are biological in origin. Living cells of plant, bacterial and animal types may be assembled. A semiconductor electrode may be patterned by masked laser light passed through the other electrode, which is transparent.

Abstract: Selected domains, normally 10.sup.3 .times.10.sup.3 such domains arrayed in a plane, within a three-dimensional (3-D) volume of active medium, typically 1 cm.sup.3 of spirobenzopyran containing 10.sup.2 such planes, are temporally and spatially simultaneously illuminated by two radiation beams, normally laser light beams in various combinations of wavelengths 532nm and 1024nm, in order, dependent upon the particular combination of illuminating light, to either write binary data to, or read binary data from, the selected domains by process of two-photon (2-P) absorption. One laser light beam is preferably directed to illuminate all domains of the selected plane in and by a one-dimensional spatial light modular (1-D SLM). The other laser light beam is first spatially encoded with binary information by 2-D SLM, and is then also directed to illuminate the domains of the selected plane.

Abstract: A random access memory addressing system utilizing optical links between memory and the read/write logic circuits comprises addressing circuits including a plurality of light signal sources, a plurality of optical gates including optical detectors associated with the memory cells, and a holographic optical element adapted to reflect and direct the light signals to the desired memory cell locations. More particularly, it is a multi-port, binary computer memory for interfacing with a plurality of computers. There are a plurality of storage cells for containing bits of binary information, the storage cells being disposed at the intersections of a plurality of row conductors and a plurality of column conductors. There is interfacing logic for receiving information from the computers directing access to ones of the storage cells. There are first light sources associated with the interfacing logic for transmitting a first light beam with the access information modulated thereon.
