Phase-change-driven dielectric-plasmonic transitions in chalcogenide metasurfaces
Chalcogenides—alloys based on group-16 ‘chalcogen’ elements (sulfur, selenium, and tellurium) covalently bound to ‘network formers’ such as arsenic, germanium, antimony, and gallium—have a variety of technologically useful ...
Lattice induced strong coupling and line narrowing of split resonances in metamaterials
Strongly coupled metamaterial resonances typically undergo mode-splitting by which there is an exchange of energy between matter excitations and photons. Here, we report a strong coupling of the lattice mode with the ...
Optical addressing of nanomechanical metamaterials with subwavelength resolution
Metamaterials that offer “on-demand” control of individual metamolecules are termed “randomly accessible metamaterials.” They can be useful for manipulation of the wavefront of electromagnetic radiation, for tailoring of ...
