Modulating photothermocapillary interactions for logic operations at the air–water interface

Abstract

We demonstrate a system for performing logical operations (OR, AND, and NOT gates) at the air–water interface based on Marangoni optical trapping and repulsion between photothermal particles. We identify a critical separation distance at which the trapped particle assemblies become unstable, providing insight into the potential for scaling to larger arrays of logic elements.
