Plasmonic Nanoparticle‐on‐Nanoslit Antenna as Independently Tunable Dual‐Resonant Systems for Efficient Frequency Upconversion

Advanced Optical Materials, EarlyView.
The nanoparticle‐on‐slit (NPoS) cavity has emerged as a sub‐wavelength platform for efficient coherent frequency conversion between mid‐infrared and visible light, and for nanoscale nonlinear vibrational spectroscopy. This numerical study identifies the NPoS quasi‐normal modes, relates them to known nanogap patterns, and predicts the relative ...

Resonance Energy Transfer and Purcell Effect in a Cu2O/Au Hybrid Optical Antenna

Advanced Photonics Research, EarlyView.
A Cu2O nanosphere mediates efficient (e.g., 70%) resonance energy transfer (RET) to a gold substrate. The RET damping constant derived from single‐particle scattering, ΓRET$\left(\Gamma\right)_{R E T}$, identifies interband transitions in Au. RET also occurs from an excited electron‐hole pair in Au to the Cu2O/Au hybrid resonator mode, followed by ...

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

Coherent Control of Thermal Radiation with Nanophotonics

Advanced Photonics Research, EarlyView.
This review explores the innovative control of thermal radiation coherence using nanophotonic structures. The fundamentals of thermal radiation, coherence control strategies (temporal, spatial, and polarization), and their applications in infrared sensing, radiative cooling, thermal camouflage, and imaging, are discussed.

Anisotropy of Second‐Harmonic Generation in SnSe Flakes with Ferroelectric Stacking

Advanced Photonics Research, EarlyView.
Giant second‐harmonic generation (SHG) susceptibility, on the order of 1000 pm V−1, in SnSe with ferroelectric stacking is demonstrated by theoretical and experimental methods. SHG microscopy is utilized to study few‐layer ferroelectric SnSe flakes on mica substrates. Stripe‐like features in SHG mapping indicate ferroelectric domains. Strong wavelength‐
