Resonant metasurfaces for generating complex quantum states [PDF]
Science, 2022 Quantum state engineering, the cornerstone of quantum photonic technologies, mainly relies on spontaneous parametric downconversion and four-wave mixing, where one or two pump photons spontaneously decay into a photon pair.

Planar chiral metasurfaces with maximal and tunable chiroptical response driven by bound states in the continuum [PDF]
Nature Communications, 2021 Optical metasurfaces with high quality factors (Q-factors) of chiral resonances can boost substantially light-matter interaction for various applications of chiral response in ultrathin, active, and nonlinear metadevices. However, current approaches lack

Integrated metasurfaces for re-envisioning a near-future disruptive optical platform
Light: Science & Applications, 2023 We organize integrated metasurfaces with conventional devices (LED, LC, MEMS, etc.), and their potential applications in VR/AR, LiDAR, and sensors. Metasurfaces have been continuously garnering attention in both scientific and industrial fields, owing to

Mechanochromic Reconfigurable Metasurfaces [PDF]
Advanced Science, 2019 AbstractThe change of optical properties that some usually natural compounds or polymeric materials show upon the application of external stress is named mechanochromism. Herein, an artificial nanomechanical metasurface formed by a subwavelength nanowire array made of molybdenum disulfide, molybdenum oxide, and silicon nitride changes color upon ...

Conformable Holographic Metasurfaces [PDF]
Scientific Reports, 2017 AbstractMetasurface holograms are typically fabricated on rigid substrates. Here we experimentally demonstrate broadband, flexible, conformable, helicity multiplexed metasurface holograms operating in the visible range, offering increased potential for real life out-of-the-lab applications.

A review of metasurfaces: physics and applications [PDF]
Reports on progress in physics. Physical Society, 2016 Metamaterials are composed of periodic subwavelength metal/dielectric structures that resonantly couple to the electric and/or magnetic components of the incident electromagnetic fields, exhibiting properties that are not found in nature.

Coherent retroreflective metasurfaces [PDF]
Physical Review Research, 2021 Inhomogeneous metasurfaces have shown possibilities for unprecedented control of wave propagation and scattering. While it is conventional to shine a single incident plane wave from one side of these metastructures, illuminating by several waves simultaneously from both sides may enhance possibilities to control scattered waves, which results in ...

Organometallic Perovskite Metasurfaces [PDF]
Advanced Materials, 2017 Organometallic perovskites, solution-processable materials with outstanding optoelectronic properties and high index of refraction, provide a platform for all-dielectric metamaterials operating at visible frequencies. Perovskite metasurfaces with structural coloring tunable across visible frequencies are realized through subwavelength structuring ...
