Advanced Emissivity Tuning Via Femtosecond Laser Surface Engineering

open access: yesAdvanced 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 ...

Inverse Design in Nanophotonics via Representation Learning

open access: yesAdvanced Optical Materials, EarlyView.
This review frames machine learning (ML) in nanophotonics through a classification based on where ML is applied. We categorize methods as either output‐side, which create differentiable surrogates for solving Maxwell's partial differential equations (PDEs), or input‐side, which learn compact representations of device geometry.

Biogenic Next‐Gen CPL Emitters: Strategies with Proteins, Polysaccharides, and Nucleotides

open access: yesAdvanced Optical Materials, EarlyView.
Biogenic molecules such as proteins, peptides, saccharides, and DNA can act as natural scaffolds for generating circularly polarized luminescence (CPL). This review highlights recent strategies exploiting these inherently chiral frameworks to achieve light emission with controllable handedness under unpolarized excitation, bridging biological ...
