On the Cover: Thin liquid film as an optical nonlinear-nonlocal medium and memory element in integrated optofluidic reservoir computer

This mutual interaction gives rise to a family of nonlinear-nonlocal effects which can be studied in the proposed chip-scale photonic circuits. The authors suggest and numerically demonstrate that optically driven liquid deformation can serve as an optical memory capable of storing information and performing neuromorphic computing in a compact actuation region. A key element in the proposed photonic platform is a nanoscale gold patch located on the optical waveguide operating as an optical heater and consequently generating thermocapillary-driven thickness changes in a liquid film covering the waveguide. The image on the cover for Advanced Photonics Volume 4 Issue 4 provides a visual rendering of the process.
