Inverse designed full-Stokes polarimetric metasurface with simultaneous wavefront sensing for visible light
Ondřej Červinka, Martin Hrtoň, Štěpán Venos +4
Metasurfaces have emerged as a powerful platform for compact optical sensors by replacing bulky lenses with flat arrays of subwavelength nanostructures. In precision optical metrol…
Optimal conditions for detecting optical dichroism at the nanoscale by electron energy-loss spectroscopy
Marek Zálešák, Martin Ošmera, Martin Hrtoň +1
The emergence of optical circular dichroism in chiral nanoscale and molecular systems provides not only a way for analyzing the sample chirality itself but also additional degrees…
SpinWaveToolkit: Python package for (semi-)analytical calculations in the field of spin-wave physics
Jan Klíma, Ondřej Wojewoda, Jakub Krčma +4
We present an open-source Python package, SpinWaveToolkit (SWT), for (semi-)analytical modeling of spin-wave dynamics in thin ferromagnetic films and exchange-coupled magnetic bila…
Establishing a library of metasurface building blocks through coherence-controlled holographic microscopy
Ondřej Červinka, Vlastimil Weiss, Martin Hrtoň +5
Digital holographic microscopy is a powerful tool for characterizing transparent and reflective phase objects. Its ability to reconstruct amplitude and phase can also offer great i…
Exploring single-photon recoil on free electrons
Alexander Preimesberger, Dominik Hornof, Theo Dorfner +4
Recent advancements in time-resolved electron and photon detection enable novel correlative measurements of electrons and their associated cathodoluminescence (CL) photons within a…
Modeling of the micro-focused Brillouin light scattering spectra
Ondřej Wojewoda, Martin Hrtoň, Michal Urbánek
Although micro-focused Brillouin light scattering (BLS) has been used for more than twenty years, it lacks a complete theoretical description. This complicates the analysis of expe…
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…
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…
Full-range optical imaging of planar collagen fiber orientation using polarized light microscopy
Michaela Turčanová, Martin Hrtoň, Petr Dvořák +5
A novel method for automated assessment of directions of collagen fibers in soft tissues is presented. It is based on multiple rotated images obtained via polarized light microscop…
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…
Plasmonic antennas with electric, magnetic, and electromagnetic hot spots based on Babinet's principle
Martin Hrtoň, Andrea Konečná, Michal Horák +2
We theoretically study plasmonic antennas featuring areas of extremely concentrated electric or magnetic field, known as hot spots. We combine two types of electric-magnetic comple…
