The Influence of the Supporting Substrate on Single‐Particle Circular Differential Scattering of DNA Assembled Nanorod Dimers

open access: yesAdvanced Optical Materials, EarlyView.
For most microscopy measurements the sample is placed on a substrate, which causes symmetry breaking, especially relevant for chiral plasmonic nanostructures. DNA origami mediated X‐shaped AuNR dimers showing high structural purity in solution, exhibit significant diversity in lineshapes and signal intensities for their circular differential scattering

High‐Tc Superinductors Through Tailored Metamaterial Losses

open access: yesAdvanced Optical Materials, EarlyView.
This work presents a loss‐engineering approach for designing high‐temperature superconducting superinductors using YBCO metamaterials. By analyzing radiative and ohmic losses through coupled‐mode theory, the study reveals that partial ohmic loss supports superinductance in thinner films.

Engineering Thermal Emission with Enhanced Emissivity and Quality Factor Using Bound States in the Continuum and Electromagnetically Induced Absorption

open access: yesAdvanced Optical Materials, EarlyView.
A metal‐based thermal metasurface supporting bound states in the continuum is demonstrated and experimentally shown to achieve a record‐high quality factor of 202 and high emissivity of 0.82. The design offers thermally stable, narrowband mid‐infrared emission, making it ideal for high‐precision gas sensing applications.

Miniaturized Single‐Photon Level Computational Complex Field Imaging System via Meta‐Optics

open access: yesAdvanced Optical Materials, EarlyView.
8192 Hadamard mask patterns generated by the digital micromirror device (DMD) are projected onto a micro target sample via a metalens. The corresponding modulated intensity spectrum encoded with the spatial information of the target is then captured by a photomultiplier tube (PMT) at the Fourier plane to recover both the amplitude and phase images ...

Dark‐State Guided‐Mode Resonance Sensors: Engineering Miniature Sensing Platforms

open access: yesAdvanced Optical Materials, EarlyView.
This research introduces compact guided‐mode resonance sensing using Gaussian‐beam‐induced symmetry breaking to excite dark states. The method generates high‐quality resonance signals in a small area, demonstrating a sensor with 128 micro‐cells and 200 nm RIU−1 sensitivity, showing potential for lab‐on‐chip and biosensing applications.
