Self‐Assembled Physical Unclonable Function Labels Based on Plasmonic Coupling

Advanced Optical Materials, EarlyView.
This article introduces advanced anti‐counterfeit labels crafted through DNA‐guided self‐assembly of plasmonic nanoparticles. Utilizing nanosphere lithography for dense and precise nanoparticle placement, these labels feature unique, unclonable optical signatures achieved through plasmonic coupling, detectable by an economical 3D‐printed dark field ...

Extreme Terahertz Nonlinearity of AlGaN/GaN‐Based Grating‐Gate Plasmonic Crystals

Advanced Optical Materials, EarlyView.
Plasmonic crystals based on grating‐gated 2D electron gas in AlGaN/GaN heterostructures provide a platform for strong light‐matter interaction. Pump‐probe experiments revealed strong terahertz nonlinearity leading to 45% increase in transmission at a fluence below 350 nJ cm−2.

Terahertz Spoof Surface Plasmon Polariton Structure for High‐Precision Gas Sensor Technology

Advanced Photonics Research, EarlyView.
This study presents a high‐sensitivity THz sensor based on spoof surface plasmon polaritons, optimized for gas sensing. The multilayer structure enables placement of the sample material in the densest region of the plasmonic surface waves, enhancing interaction with THz waves and significantly improving sensitivity to small refractive index variations ...

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

High‐Quality‐Factor, Compact Nanoplasmonic Filter Utilizing Graphene Metasurface at Near‐Infrared Range

Advanced Photonics Research, EarlyView.
A plasmonic reflective filter utilizing monolayer graphene is proposed and theoretically examined. The filter demonstrates dual‐band reflection and absorption characteristics at resonance wavelengths in the near infrared. The reflection dips is adjusted by manipulating the chemical potential of graphene.
