Tunable hyperbolic metamaterials for brightening single-photon emission
Manobina Karmakar, Pavel Klok, Filip Ligmajer +1
Hyperbolic metamaterials (HMMs) are widely used to enhance spontaneous emission through their exceptionally large photonic density of states, yet large Purcell factors (>100) rarel…
Chiral nanoparticle chains on inorganic nanotube templates
Lukáš Kachtík, Daniel Citterberg, Kristýna Bukvišová +7
Fabrication of chiral assemblies of plasmonic nanoparticles is a highly attractive and challenging task with promising applications in light emission, detection, and sensing. So fa…
Phase-resolved optical characterization of nanoscale spin waves
Ondřej Wojewoda, Martin Hrtoň, Meena Dhankhar +7
We study theoretically and experimentally the process of Brillouin light scattering on an array of silicon disks on a thin Permalloy layer. We show that phase-resolved Brillouin li…
Pulsed laser deposition of Sb2S3 films for phase-change tunable nanophotonics
Peter Kepič, Petr Liška, Beáta Idesová +3
Non-volatile phase-change materials with large optical contrast are essential for future tunable nanophotonics. Antimony trisulfide (Sb2S3) has recently gained popularity in this f…
Observing high-k magnons with Mie-resonance-enhanced Brillouin light scattering
Ondřej Wojewoda, Filip Ligmajer, Martin Hrtoň +8
Magnonics is a prospective beyond CMOS technology which uses magnons, the quanta of spin waves, for low-power information processing. Many magnonic concepts and devices were recent…
Optically tunable Mie-resonance VO2 nanoantennas for metasurfaces in the visible
Peter Kepič, Filip Ligmajer, Martin Hrtoň +4
Metasurfaces are ultrathin nanostructured surfaces that can allow arbitrary manipulation of light. Implementing dynamic tunability into their design could allow the optical functio…
Single-Shot Orientation Imaging of Nanorods Using Spin-to-Orbital Angular Momentum Conversion of Light
Tomáš Fordey, Petr Bouchal, Michal Baránek +7
The key information about any nanoscale system are orientations and conformations of its parts. Unfortunately, these details are often hidden below the diffraction limit and elabor…
Independent engineering of individual plasmon modes in plasmonic dimers with conductive and capacitive coupling
Vlastimil Křápek, Andrea Konečná, Michal Horák +5
We revisit plasmonic modes in nanoparticle dimers with conductive or insulating junction resulting in conductive or capacitive coupling. In our study which combines electron energy…
Silver Amalgam Nanoparticles and Microparticles: A Novel Plasmonic Platform for Spectroelectrochemistry
Filip Ligmajer, Michal Horák, Tomáš Šikola +2
Plasmonic nanoparticles from unconventional materials can improve or even bring some novel functionalities into the disciplines inherently related to plasmonics such as photochemis…
Geometric-phase microscopy for high-resolution quantitative phase imaging of plasmonic metasurfaces with sensitivity down to a single nanoantenna
Petr Bouchal, Petr Dvořák, Jiří Babocký +8
Optical metasurfaces have emerged as a new generation of building blocks for multi-functional optics. Design and realization of metasurface elements place ever-increasing demands o…
