Light–Matter Interactions in Hybrid Material Metasurfaces

Abstract

This Review focuses on the integration of plasmonic and dielectric metasurfaces with emissive or stimuli-responsive materials for manipulating light–matter interactions at the nanoscale. Metasurfaces, engineered planar structures with rationally designed building blocks, can change the local phase and intensity of electromagnetic waves at the subwavelength unit level and offers more degrees of freedom to control the flow of light. A combination of metasurfaces and nanoscale emitters facilitates access to weak and strong coupling regimes for enhanced photoluminescence, nanoscale lasing, controlled quantum emission, and formation of exciton–polaritons. In addition to emissive materials, functional materials that respond to external stimuli can be combined with metasurfaces to engineer tunable nanophotonic devices. Emerging metasurface designs including surface-functionalized, chemically tunable, and multilayer hybrid metasurfaces open prospects for diverse applications, including photocatalysis, sensing, displays, and quantum information.

Classical nexus between chiral inducers and achiral silver nanoparticles and integration of the digital XOR logic gate

“…We further employed circular dichroism (CD) spectroscopy, which is a very useful technique for the characterization of chiroptical properties. 50,51 A controlled experiment performed with L/D-Cys (racemic mixture)capped AgNPs showed a flat line in the CD signal due to the nullified chiroptical behavior of AgNPs (Fig. S7a, ESI †).…”

Beyond Conventional Sensing: Hybrid Plasmonic Metasurfaces and Bound States in the Continuum

“…Bound states in the continuum have potential applications in various areas, such as sensing, optical filtering, laser technology, nonlinear photonics, and coherent light generation [ 23 , 24 , 25 , 29 ]. Since the 1980s, strong mode coupling leading to their splitting (so-called Rabi splitting) in the spectra of atomic and quantum systems has attracted great attention from researchers, and this phenomenon has gained increasing interest in nanophotonics in recent years [ 30 , 31 , 32 , 33 , 34 , 35 , 36 ]. Initially proposed and observed in atomic and molecular systems, Rabi splitting occurs in a strong coupling regime where the energy frequently oscillates between a single photon and a two-level quantum emitter leading to the splitting of the spectra of the scattering parameters of the quantum emitter in a high Q -factor cavity [ 30 , 31 , 32 , 33 ].…”

Therefore, Rabi splitting occurs in the realm of strong coupling where the coherent energy exchange rate between the emitter and matter exceeds its energy dissipation rate, which causes anti-crossing in the dispersion relation of the system.…”

Synthesis of Dielectric Nanospheres with Moderate‐Refractive‐Index and Applications in Photon Manipulating

“…Both the initial use of signal fire and the current optical fiber network are the direct embodiment of the utilization of light‐matter interactions [2] . With the proposition and establishment of quantum and electrodynamic theories, the mechanism of the light‐matter interaction is gradually clear [3] . When light passes through a matter, electrons, ions, or charges of molecules in the matter will undergo forced vibration under the action of the incident photoelectric vector [4] .…”

“…[2] With the proposition and establishment of quantum and electrodynamic theories, the mechanism of the light-matter interaction is gradually clear. [3] When light passes through a matter, electrons, ions, or charges of molecules in the matter will undergo forced vibration under the action of the incident photoelectric vector. [4] If the light energy is partially absorbed by the material and converted into other energy forms, this interaction is called absorption effect.…”
