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.

On the Cover: Dynamic coloration of polymerized cholesteric liquid crystal networks by infiltrating organic compounds

Recently, the research group led by Prof. Lu-Jian Chen at Xiamen University (XMU) achieved real-time continuous modulation of the working wavelength in anisotropic polymerized CLC (PCLC) films with a dynamic range of up to 210 nm by using a microfluidics-based "wash-out/refill" strategy. They also demonstrated structural color patterns with reversible changes and multipitch gradients. This work was published in Chinese Optics Letters 2022, Vol. 20, No. 9 (Y. Cao, et al., Dynamic coloration of polymerized cholesteric liquid crystal networks by infiltrating organic compounds) and was selected as the cover of the issue.

On the Cover: Unidirectional bound states in the continuum in Weyl semimetal nanostructures

Bound states in the continuum (BICs) enable perfect wave localization and significantly enhance light–matter interactions although systems are optically open. Those trapped modes without the leaky-wave radiation in an open continuum are important in numerous applications, including optical nonlinearity, light emitters, and nano-sensors.
