Engineering correlated disorder for tailored light scattering
Denis Langevin, Emma Bosbaty-Galliot, Emmanuel Centeno +5
Correlated disorder is known to shape light scattering in ways uncorrelated disorder cannot, from hyperuniform transparency to the structural colors of naturally occurring structur…
Anoplophora graafi Longhorn Beetle Coloration is due to Disordered Diamond-like Packed Spheres
Kenza Djeghdi, Cedric Schumacher, Ilja Gunkel +2
While artificially photonic materials are typically highly ordered, photonic structures in many species of birds and insects do not possess a long-range order. Studying their order…
Efficient structural color from pigment-loaded nanostructures
Tianqi Sai, Luis S. Froufe-Pérez, Frank Scheffold +2
Color can originate from wavelength-dependence in the absorption of pigments or the scattering of nanostructures. While synthetic colors are dominated by the former, vivid structur…
X-ray nanotomography reveals formation of single diamonds by block copolymer self-assembly
Kenza Djeghdi, Dmitry Karpov, S. Narjes Abdollahi +14
Block copolymers are recognised as a valuable platform for creating nanostructured materials with unique properties. Morphologies formed by block copolymer self-assembly can be tra…
High-resolution three-dimensional imaging of topological textures in single-diamond networks
Dmitry Karpov, Kenza Djeghdi, Mirko Holler +14
Highly periodic structures are often said to convey the beauty of nature. However, most material properties are strongly influenced by the defects they contain. On the mesoscopic s…
3D tomographic analysis of the order-disorder interplay in the Pachyrhynchus congestus mirabilis weevil
Kenza Djeghdi, Ullrich Steiner, Bodo D. Wilts
The bright colors of Pachyrhynchus weevils originate from complex dielectric nanostructures within their elytral scales. In contrast to previous work exhibiting highly ordered sing…
Unconventional bound states in the continuum from metamaterial induced electron-acoustic plasma waves
Wenhui Wang, Antonio Günzler, Bodo D. Wilts +1
Photonic bound states in the continuum are spatially localised modes with infinitely long lifetimes that exist within a radiation continuum at discrete energy levels. These states…
Enhancing the Refractive Index of Polymers with a Plant-Based Pigment
Mohammad Yasir, Tianqi Sai, Alba Sicher +4
Polymeric materials are prized for their formability, low density, and functional versatility. However, the refractive indices of common polymers fall in a relatively narrow range…
Strong Circular Dichroism in Single Gyroid Optical Metamaterials
Cédric Kilchoer, Narjes Abdollahi, James A. Dolan +6
Over the past two decades, metamaterials have led to an increasing number of biosensing and nanophotonic applications due to the possibility of a careful control of light propagati…
Designing Refractive Index Fluids using the Kramers-Kronig Relations
Tianqi Sai, Matthias Saba, Eric R. Dufresne +2
For a number of optical applications, it is advantageous to precisely tune the refractive index of a liquid. Here, we harness a well-established concept in optics for this purpose.…
Evolutionary algorithms converge towards evolved biological photonic structures
Mamadou Aliou Barry, Vincent Berthier, Bodo D. Wilts +6
Nature features a plethora of extraordinary photonic architectures that have been optimized through natural evolution. While numerical optimization is increasingly and successfully…
