Reversible computing: All-optical implementation of interaction and priese gates

Abstract

Integrated optics offers a particularly interesting candidate for implementing parallel, reversible computing structures operating in closer correspondence with the underlying microphysical laws which presume nondissipative interactions and global interconnections. An implementation of the computation-universal Interaction Gate is described, based upon Kaplan's bistable nonlinear interface. The gate, together with an optical crossover using a half-wave plate, comprise a construction-universal set. © 1987.
