Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

Advanced Photonics Research, EarlyView.
This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

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.

Bound States in the Continuum in Metasurface Absorbers: A Comparison with Metasurfaces

Advanced Photonics Research, EarlyView.
Bound states in the continuum (BICs) offer a powerful mechanism for enhancing light–matter interactions. This work systematically investigates the radiation characteristics of BICs under both transmission and reflection configurations using multipolar analysis.

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.
