Electrical Generation of Surface Plasmon Polaritons in Plasmonic Heterostructures
Surface plasmon polaritons (SPPs) can be understood as two-dimensional light confined to a conductor-dielectric interface via plasmonic excitations. While low-energy SPPs behave similarly to photons, higher-frequency SPPs resemble surface plasmons. Electrically generating mid-range SPPs is particularly challenging because it requires compensating for ...

Scalable Room‐Temperature Terahertz Graphene Cameras
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Numerical modeling of mesoscopic material response models that capture the quantum dynamics of electrons does not have to come with discouraging computational bottlenecks. The main message is that through a shift in perspective in modeling toward integral equation methods and exploiting symmetry‐based arguments, it is possible to capture complicated ...

Dynamical Modulation of Dual‐Band Thermal Emission in a Graphene‐2D‐hBN‐LiV2O5 Heterostructure
A van der Waals heterostructure combining graphene, 2D‐hBN, and LiV2O5 enables dynamically tunable dual‐band mid‐infrared thermal emission with narrow spectral features. Plasmon–phonon strong coupling yields five hybrid polariton branches, whereas coupled‐oscillator models quantify mode mixing and Rabi splittings (up to 27.72 meV via hBN‐thickness ...

A hybrid‐structured pentagonal‐core photonic crystal fiber sensor operating in the terahertz regime is proposed for fuel adulteration detection. Numerical analysis using the finite element method in COMSOL shows optimal performance at 2 THz, achieving high relative sensitivity (up to 98.20%) with ultralow confinement loss (~10−¹³ dB/m). The design also

We demonstrate ultrafast coherent manipulation of the normal mode splitting in metal/molecular-aggregate nanostructures by real-time observation of Rabi oscillations between excitons and surface-plasmon-polaritons. Oscillations in exciton density on a 10-

Quantum Dynamics Simulations of Polariton Transport in a Bloch Surface Wave Cavity
Polariton Transport Quantum Dynamics for molecules (purple dots) collectively coupled to a Bloch Surface Wave Cavity. Lower panels show the polariton dispersion relation. ABSTRACT Coupling excitons to quantized cavity photonic modes can significantly enhance the spatial and temporal range of excitonic transport.

Transmission of surface plasmon polaritons through atomic-size constrictions
We study the excitation and propagation of surface plasmon polaritons (SPPs) on a micron-sized thin gold stripe. Grating couplers are embedded for both excitation of SPPs and detection after propagation.
