Multiresonant Plasmonics with Spatial Mode Overlap
Plasmonic nanostructures can enhance light-matter interactions in the subwavelength domain, which is useful for photodetection, light emission, optical biosensing, and spectroscopy. However, conventional plasmonic devices are optimized to operate in a single wavelength band, which is not efficient …

Probing Coherent States and Nonlinear Properties in Multifunctional Material Systems
… [4], n-type InAsP films [5, 6], and nanolaminate plasmonic crystals [7]. Probing multiferroics, which are materials that can exhibit ferromagnetic, ferroelectric, and ferroelastic orders simultaneously in a single phase, was a main focus of this study. BiFeO3 (BFO) is the most widely investigated …

Interactions of Organic Fluorophores with Plasmonic Surface Lattice Resonances
… the strongest plasma oscillations are known as “plasmonic” metals. In terms of pure elements, the most plasmonic metals are, canonically, copper, silver, and gold. But there are several others that are known to be plasmonic, namely aluminum, gallium, and indium, as well as the alkali metals, …
