… There is a growing interest among the optical computing community to realize binary
digital operations using photons as the primary signal-carrying medium. In this article, a
novel technique involving a colloid medium is used for realizing three all-optical logic gates.
It is known that colloidal particles which have an index of refraction different from that of the
supporting solvent will order into rows of particles under the influence of radiation pressure
caused by crossed laser beams …

Abstract
An all‐optical technique is used to realize three logic operations, AND, X‐OR, and NOT. The logic inputs are represented by laser beams that are made to cross in a sample of polymer microspheres at predetermined angles.
