3D Meta‐Atoms for High Confinement of Mid‐IR Radiation
Advanced Optical Materials, EarlyView.Mid‐infrared, three‐dimensional circuit‐like resonators with extreme field confinement are experimentally demonstrated. Combining simulations, measurements, and analytical modelling, a physical interpretation and prediction of the resonant modes supported by the structure, including their resonant frequency and radiative and non‐radiative losses, is ...

Advanced Emissivity Tuning Via Femtosecond Laser Surface Engineering
Advanced Optical Materials, EarlyView.Femtosecond laser surface processing (FLSP) is employed to fabricate titanium‐based metamaterials with engineered micro/nano‐scale features that exhibit spectrally selective and omnidirectional thermal emissivity. By integrating advanced ellipsometry, electromagnetic modeling, and compositional analysis, the work reveals resonance‐driven emissivity ...

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.

Numerical and Experimental Methods for Estimating the Propagation Loss in Microphotonic Waveguides
Advanced Photonics Research, EarlyView.Finite‐element finite‐difference time domain, eigenmode‐expansion, and volume‐current simulations are benchmarked against cut‐back, ring‐resonator, and OFDR measurements to quantify waveguide propagation loss in integrated photonic circuits. Scattering, absorption, leakage, and back‐reflection contributions are dissected; error sources are ranked; and ...
