Raman scattering of phonon polaritons under nanoscale confinement: the role of structure and environment
George Zograf, Betul Kucukoz, Oleg Kotov +10
Strong light-matter coupling gives rise to polaritons -- quasiparticles that combine both photonic and material characteristics. Here, we show that polar nanocrystals exhibit struc…
Combining ultrahigh index with exceptional nonlinearity in resonant transition metal dichalcogenide nanodisks
George Zograf, Alexander Yu. Polyakov, Maria Bancerek +3
Second-order nonlinearity in solids gives rise to a plethora of unique physical phenomena ranging from piezoelectricity and optical rectification to optical parametric amplificatio…
Multilayer metamaterial absorbers inspired by perfectly matched layers
Anna Pastuszczak, Marcin Stolarek, Tomasz J. Antosiewicz +1
We derive periodic multilayer absorbers with effective uniaxial properties similar to perfectly matched layers (PML). This approximate representation of PML is based on the effecti…
Oscillatory optical response of amorphous plasmonic nanoparticle arrays
Tomasz J. Antosiewicz, S. Peter Apell, Michael Zach +2
The optical response of metallic nanoparticle arrays is dominated by localized surface plasmon excitations and is the sum of individual particle contributions modified by inter-par…
