Fano resonances result from the strong coupling and interference between a broad background state and a narrow, almost discrete state, leading to the emergence of asymmetric scattering spectral profiles. Under certain conditions, Fano resonances can

We investigate the scattering properties of a paired periodic array of silver-dielectric metasurfaces. We report Fano resonances and Rabi splitting in the spectral response of the scattering parameters. We show that tuning the refractive index of the

We design and analyze the optical properties of multilayered metal-dielectric fishnet metastructures using fullwave numerical simulations. We report negative refraction at the infrared spectral range with low loss. Most previous studies reported nega

We study the resonant response of a hybrid plasmonic-dielectric lattice and analyze mode coupling induced by the periodic arrangement. We design scattering elements out of multi-segment nanostructure allowing for subwavelength light confinement, and

CdSexS1-x/ZnS quantum dots (QDs) can cover a broader spectral range than the commonly used CdSe/ZnS QDs and are potentially useful as biomarkers for tagging cell lines such as HeLa, A549, and MCF-7 due to their high photoluminescence intensity and st

Anti-Stokes photoluminescence from colloidal CdSeS/ZnS quantum dots (QDs) is observed. The QDs were inserted into the core of wider-bandgap SiO2/Si3N4/SiO2 structure by thin film deposition and confirmed as promising nanoemitters for laser cooling du
