Directionally Asymmetric Holographic Imaging for Arbitrary Polarization States Using Janus Metasurfaces

Advanced Optical Materials, EarlyView.
We demonstrate single‐layer titanium dioxide Janus metasurface holograms that achieve directionally asymmetric imaging under forward and backward illumination. By integrating the Dammann grating principle with precise phase control, our design produces high‐fidelity holographic images for arbitrary polarization states at 532 nm, simplifying fabrication,

Ordered arrays of metal nanostructures on insulator/metal film: dependence of plasmonic properties on lattice orientation

Nano Express
We study the dependence of the optical response of square lattices of plasmonic nanoparticles on the mutual orientation of the lattice and the plane of incidence of illuminating light.

Integration of Laser‐Patterned Photonic Crystals in Si Solar Cells

Advanced Optical Materials, EarlyView.
Photonic crystal textures are integrated into silicon solar cells using laser‐patterned alumina masks and plasma etching. An isotropic defect‐removal process preserves surface passivation and optical quality, enabling 23.1% efficiency. This scalable process with periodically anchored masks and Bessel‐beam patterning marks an important step toward ...

Next Generation of Thermal Barrier Coatings with High Temperature Metal‐Silicide Metamaterials

Advanced Optical Materials, EarlyView.
Thermal metamaterials have emerged as a powerful platform in the engineering of radiative heat transfer across a broad range of applications, including thermal imaging, passive cooling, and thermo‐photovoltaics. Here, a novel application is presented for metamaterials: thermal dual barrier coatings (TDBCs).

Origin of Ultraviolet‐Induced High‐Temperature Photovoltaic Response at Pt/Gd‐Doped CeO2 Interface

Advanced Optical Materials, EarlyView.
Oxygen uptake induced by UV irradiation generates an oxygen chemical potential gradient across acceptor‐doped ceria at high temperatures. Besides the photovoltage caused by band bending at the heterojunction interface, the observed voltage can also be attributed to the Nernst voltage arising from the oxygen potential gradient.

A new technique for oil backstreaming contamination measurements [PDF]

Due to the large size and the number of diffusion pumps, space simulation chambers cannot be easily calibrated by the usual test dome method for measuring backstreaming from oil diffusion pumps.

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 ...
