A Near Infrared Emission Feature from Visible Fluorescence Tails and its Correlation with Singlet Oxygen

Advanced Optical Materials, EarlyView.
A persistant NIR emission tail and feature at 923 nm is observed during photochemical singlet oxygen generation using various photosensitizers. While initially considered as singlet oxygen phosphorescence we show that it arises from the NIR‐tail of (visible) photosensitizer emission and the non‐linear increase of detector sensitivity.

Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index

Advanced Photonics Research, EarlyView.
Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.

An Ultra‐Wideband Metasurface Perfect Absorber Based on Hybrid Absorption Modes

Advanced Photonics Research, EarlyView.
A Ge2Sb2Te5 metasurface absorber enables polarization‐independent, ultrabroadband (UV–NIR) light absorption with high angular tolerance. Its performance stems from overlapping electric and magnetic dipole resonances in a symmetric structure, achieving 94% average absorption and maintaining 83% even at 70° incidence, promising for integrated ...

Enhanced Trapping with an Optimized Graphene‐Based Bowtie Plasmonic Nanotweezer: Design, Analysis, and Bioanalytical Applications

Advanced Photonics Research, EarlyView.
A graphene‐based bowtie plasmonic nanotweezer is designed and optimized using particle swarm optimization and transfer matrix analysis. The structure achieves strong field confinement, delivering trapping forces up to 6 nN W−1 for 10 nm bioparticles with sixfold lower power requirements than conventional designs.

On–Off Switchable Micromotors for Use in Steerable Microvehicles

Advanced Robotics Research, EarlyView.
Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,
