Polarization-Controlled Chromo-Encryption
Olivier Martin, Hsiang-Chu Wang
The response of simple plasmonic nanorods to polarized illumination is studied in detail. Depending on the orientation of that polarization with respect to the symmetry axes of the nanostructure, a chiral response can occur, which can be analyzed through a ...
WILEY-V C H VERLAG GMBH2023Dielectric Tetramer Nanoresonators Supporting Strong Superchiral Fields for Vibrational Circular Dichroism Spectroscopy
Hatice Altug, Felix Ulrich Richter, Yasaman Jahani, Rui Lu, Bang Hyun Lee, Ming-Lun Tseng, Longfang Ye
Chirality (C) is a fundamental property of objects, in terms of symmetry. It is extremely important to sense and distinguish chiral molecules in the fields of biochemistry, science, and medicine. Vibrational circular dichroism (VCD) spectroscopy, obtained ...
Washington2023Layered metals as polarized transparent conductors
Philip Johannes Walter Moll, Maja Deborah Bachmann, Matthias Carsten Putzke, Chunyu Guo
The quest to improve transparent conductors balances two key goals: increasing electrical conductivity and increasing optical transparency. To improve both simultaneously is hindered by the physical limitation that good metals with high electrical conducti ...
NATURE PORTFOLIO2023Multipolar Pseudochirality-Induced Optical Torque
Olivier Martin, Karim Achouri, Andrei Kiselev, Mintae Chung
It has been observed that achiral nanoparticles, such as flat helices, may be subjected to an optical torque even when illuminated by normally incident linearly polarized light. However, the origin of this fascinating phenomenon has so far remained mostly ...
Washington2023Spatial symmetries in nonlocal multipolar metasurfaces
Olivier Martin, Karim Achouri, Ville Tuovi Tiukuvaara
We propose a framework that connects the spatial symmetries of a metasurface to its material parameter tensors and its scattering matrix. This provides a simple and universal way to effortlessly determine the properties of a metasurface scattering response ...
SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERS2023Optical metasurfaces: synthesis, nanofabrication, and colorful applications
In this thesis, we mainly utilize silver to construct the meta-atoms. Although suffering from easily oxidized, its excellent lossless property throughout the visible range makes it suitable for study. When preserved properly, silver-made metasurfaces can s ...
EPFL2022Observational signatures of galactic turbulent dynamos
We analyse the observational signatures of galactic magnetic fields that are self-consistently generated in magnetohydrodynamic simulations of the interstellar medium through turbulence driven by supernova (SN) explosions and differential rotation. In part ...
OXFORD UNIV PRESS2022Thermally reconfigurable metalens
Giulia Tagliabue, Fateme Kiani Shahvandi, Anna Archetti, Theodoros Tsoulos, Nathanaël Restori, Ren-Jie Lin
Reconfigurable metalenses are compact optical components composed by arrays of meta-atoms that offer unique opportunities for advanced optical systems, from microscopy to augmented reality platforms. Although poorly explored in the context of reconfigurabl ...
WALTER DE GRUYTER GMBH2022Pitfalls in the spectral measurements of polarization-altering metasurfaces
Olivier Martin, Hsiang-Chu Wang
The optical characterization of metasurfaces and nanostructures that alter the polarization of light is tricky and can lead to unphysical results, such as reflectance beyond unity. We track the origin of such pitfalls to the response of some typical optica ...
Optica Publishing Group2022Asymmetric Metal-Dielectric Metacylinders and Their Potential Applications From Engineering Scattering Patterns to Spatial Optical Signal Processing
Romain Christophe Rémy Fleury, Ali Momeni, Mahdi Safari
We propose a bianisotropic hybrid metal-dielectric structure comprising dielectric and metallic cylindrical wedges wherein the composite metacylinder enables advanced control of electric, magnetic, and magnetoelectric resonances. We establish a theoretical ...
