ABSTRACT:
An optical memory cell constructed from an optical combiner, a 1.times.2 optical swtich and optical fibers. One input port of the optical combiner serves as the input to the memory cell. The output port of the optical combiner is connected to the input of the optical switch by an optical fiber. A first output port of said switch is connected by an optical fiber to the second input of the optical combiner, such that when said switch is in the straight-through state, an optical loop is formed through which an optical pulse can circulate. The second output of the optical switch serves as the output of the memory cell when said optical switch is in the cross-over state. Control signals are provided by a clock.
