Additive and Subtractive Color Filters Based on Birefringent Dielectric Metasurfaces
Ondřej Červinka, Filip Ligmajer, Ondřej Brunn +3
Dielectric metasurfaces offer a path to high-efficiency optical components at the sub-wavelength scale. In this work, we utilize the wavelength-dependent birefringence of TiO2 nano…
Reconfigurable plasmonic hot spots enabled by composite VO2-gold plasmonic antennas
Rostislav Řepa, Jiří Kabát, Tomáš Šikola +1
We theoretically investigate the formation of electric and magnetic hot spots with reconfigurable plasmonic antennas. We consider three material systems offering different levels o…
Plasmonic lightning-rod effect
Vlastimil Křápek, Rostislav Řepa, Michael Foltýn +2
The plasmonic lightning-rod effect refers to the formation of a strong electric near field of localized surface plasmons at the sharp features of plasmonic antennas. While this eff…
Correlative electron and light spectroscopy of strongly-coupled mid-infrared plasmon and phonon polaritons
Pavel Gallina, Andrea Konečná, Jiří Liška +2
The ability to control and modify infrared excitations in condensed matter is of both fundamental and application interests. Here we explore a system supporting low-energy excitati…
