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 ...
Plasmonics of topological insulators at optical frequencies
The development of nanoplasmonic devices, such as plasmonic circuits and metamaterial superlenses in the visible to ultraviolet frequency range, is hampered by the lack of low-loss plasmonic media. Recently, strong plasmonic ...
Spontaneous natural optical activity in disordered media
We theoretically demonstrate natural optical activity in disordered ensembles of nonchiral plasmonic resonators. We show that the statistical distributions of rotatory power and spatial dichroism are strongly dependent on ...
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 ...
