Spacer‐Less Substrate‐Integrated Metasurface for Near‐Unity Terahertz Absorption

Advanced Optical Materials, Volume 14, Issue 29, 7 August 2026.
ABSTRACT Although conventional metal‐insulator‐metal (MIM) terahertz (THz) absorbers can provide near‐unity absorption, their multilayer stacks inevitably introduce additional thickness, mass, and residual stress, which limit their compatibility with THz thermal sensing platforms.

Extreme Polaritonic Interactions in a Room‐Temperature Designable Sub‐Nanocavity Quantum Electrodynamic Platform

Advanced Science, Volume 13, Issue 44, 7 August 2026.
 A nanoparticle‐cluster‐on‐mirror (NPcoM) serves as a functionally deterministic sub‐nanocavity that emulates picocavities, enabling extreme light–matter interactions and polaritonic phenomena. ABSTRACT Pushing nanoscale optical confinement to its ultimate limits defines the regime of nano‐cavity quantum electrodynamics (nano‐cQED), where light‐matter ...

High‐Performance Near‐Infrared Organic Light‐Emitting Diodes Based on Grating‐Structured Hole Transport Layer

Small Structures, Volume 7, Issue 8, August 2026.
High‐performance near‐infrared (NIR) organic light‐emitting diodes (OLEDs) were achieved by incorporating a one‐dimensional Bragg grating into a thermally cross‐linkable hole‐transporting layer via microtransfer molding. The optimized devices exhibit an emission peak at 880 nm, a maximum external quantum efficiency of 1.55%, and a peak radiant exitance

Electrical excitation of surface plasmon polaritons

, 2009
A surface plasmon polariton (SPP) is an electromagnetic wave propagating at the interface between a metal and a dielectric material. The two-dimensional confinement of SPPs and the tunability of their dispersion enable optical functionality that cannot be achieved with regular dielectrics.

Waveguiding with Surface Plasmon Polaritons

Reports on Progress in Physics, 2014
Surface plasmon polaritons (SPPs) are electromagnetic modes propagating along metal-dielectric interfaces. Various SPP modes can be supported by flat and curved, single and multiple surfaces, exhibiting remarkable properties, including the possibility of concentrating electromagnetic fields beyond the diffraction limit, i.e., on the nanoscale, while ...
