Temperature‐Dependent Zinc Oxide Cathodoluminescence: Toward Compact Wavelength‐Tunable Solid‐State Photoionization Sources

Advanced Optical Materials, EarlyView.
A proof‐of‐concept of a thermally‐tunable cathodoluminescence‐based light source is demonstrated using a wide‐bandgap z‐cut ZnO crystal as anode, resulting in the ultraviolet (UV) emission peak shifting from 398 nm to ~409 nm (3.115‐3.032 eV). Our results establish the feasibility of a compact, field‐deployable UV source with potential for gas sensing ...

Ferroelectric Fluids for Nonlinear Photonics: Evaluation of Temperature Dependence of Second‐Order Susceptibilities

Advanced Optical Materials, EarlyView.
Nonlinear optical susceptibilities of five different materials that exhibit the ferroelectric nematic phase, as well as smectic A ferroelectric phase, are determined. The materials investigated include archetypal molecular architectures as well as mixtures showing room‐temperature ferroelectric phases.

Photonics of Topological Magnetic Textures

Advanced Optical Materials, EarlyView.
Localized noncollinear magetic textures imprint their geometry and topology onto traversing photonic fields endowing them with orbital angular‐momentum, chirality, and magnetoelectric densities. Abstract Topological textures in magnetically ordered materials are an important case studies for fundamental research with promising applications in data ...

Selective Crystal Growth and Optical Responses of 2H and 3R Polytypes in van der Waals Polar Insulator α‐In2Se3

Advanced Optical Materials, EarlyView.
Selective growth protocols are established to obtain high‐quality bulk single crystals of the 2H and 3R polytypes of the vdW polar insulator α‐In2Se3, together with rapid, non‐destructive phase‐identification methods. Combined optical transmission and absolute reflectivity measurements, supported by DFT calculations, reveal distinct polytype‐dependent ...

Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index

Advanced Photonics Research, EarlyView.
Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.
