TL;DR: Liquid crystals (LCs)-integrated metaholograms for ultracompact dynamic holographic displays are proposed, which will provide a path to external stimuli-driven "smart" sensing and display applications such as hologram labels for temperature/pressure/touch monitoring and interactive holographic shows with haptic motion recognition.

TL;DR: In this paper, a review of optical and acoustic metamaterials in the past 15 years is presented, which may lead to exciting applications in communications, sensing, and imaging.

TL;DR: In this article, the authors exploit polycrystalline silicon to achieve both fabrication compatibility and hologram functionality at the wavelength of 532 nm, which is a significant reduction of optical power at visible wavelengths.

TL;DR: By designing plasmonic nanostructures exhibiting multimodal phonon interference, this work can detect the spatial properties of complex phonon modes below the optical wavelength through the interplay between plasmons and phonons and allows detection of complex nanomechanical dynamics by polarization-resolved transient absorption spectroscopy.

TL;DR: This work identifies and characterize the mechanisms behind each and provides a framework that can be used to design any all-dielectric metasurfaces of subwavelength Mie scatterers for spectral modulation.
