摘要： In a multistable optical logic element with a light-sensitive organic material (1) which undergoes a photocycle with several physical states by irradiation with light, and wherein a physical state is assigned a logical value which can be changed by addressing the element optically, the element initially before the addressing is in a metastable state generated in advance. A multistable optical logic element has been made proximity-addressable by providing at least a colour light source (1) for optical addressing and at least one colour-sensitive optical detector (5) adjacent to the light-sensitive material. In a method for preparing of the light-sensitive material (1) a desired initial metastable state is generated in the photocycle and assigned a determined logical value for the element. In a method for optical addressing of the optical logic element steps for respectively writing and storing, reading, erasing and switching comprises generating transitions between states in the photocycle and detection of the states. Use in an optical logical device for storing and processing of data.

摘要： Zwecks Verstärkung optischer Signale und zwecks Erhöhung der Schwellensensibilität optischer Elemente gegenüber Eingangssignalen und zwecks Steuerung des Kommutierens von Kanälen der Ausgangsstrahlung wird ein nichtlineares optisches Element vorgeschlagen, der einen nichtlinearen Phasenmodulator (1), Halbleiterlaser (3) und Spiegel (6, 7, 8) enthält. Die Verstärkung der Leistung optischer Signale wird durch das Vorhandensein aktiver Laserelemente (3) gewährleistet. Das Kommutieren der Kanäle erfolgt durch das Einschalten von Injektionsströmen der entgegengesetzten Laser (3), die an ein- und derselben Achse gelegen sind, und durch optische Spiegelverschlüsse (2), die sich in der gleichen Achse befinden.

摘要： Method and apparatus for making a plurality of reflection holograms (101-109) positioned in a two-dimensional array to interconnect optically a plurality (120) of optically nonlinear optical devices (121-129) also positioned in a two-dimensional array. The devices are operated to function as optical logic NOR gates, and the reflection holograms optically interconnect the devices to form any desired optical logic circuit such as a clocked JK sequential logic flip-flop circuit. The reflection holograms are made by affixing the devices and a photosensitive material (500) to the opposite surfaces of a layer of transparent material (505). The transparent material maintains the positions of the devices relative to the photosensitive material both before and after the hologram is made. Spatial light modulator masks (501, 502) are temporarily placed over the outside surfaces of the photosensitive material and the devices to mask all but selected areas of the photosensitive material and designated devices from being illuminated by coherent light beams.
