Abstract
A number of first digital optical circuits have been demonstrated: (1) A three-element loop in which a lock-and-clock architecture is used to process, store, reset, and propagate around the loop. By use of three-fold fan-in, this basic circuit demonstrates (a) restoring optical logic using off-axis address and (b) the negation process (a necessity for computation). (2) The operation of an all-optical digital full adder in which a reflection nonlinear element is used as a discriminator.
