High‐Resolution Electron‐Beam Poling of X‐Cut Lithium Niobate Thin Films

Advanced Optical Materials, EarlyView.
A new periodic poling technique using electron beams to create stable, high‐quality ferroelectric patterns is developed in x‐cut thin‐film lithium niobate (TFLN). The method works at room temperature with both standard and MgO‐doped materials, affords ferroelectric domain pitches as small as 375 nm, and lends itself to seamless integration with state ...

Precision‐Engineered Plasmonic Nanostar Arrays for High‐Performance SERS Sensing

Advanced Optical Materials, EarlyView.
Highly ordered and dose‐controlled arrays of gold nanodiscs are created using the dots‐on‐the‐fly EBL technique and subsequently converted into nanostar arrays. This technique unlocks the reproducible and robust fabrication of highly efficient SERS substrates. Abstract Surface‐enhanced Raman scattering (SERS) spectroscopy has emerged as a powerful tool

Development of High‐Performance Multilayer Monochromators

Advanced Optical Materials, EarlyView.
Detailed insights into the optical and multilayer design of Double Multilayer Monochromators (DMM) are presented and fully characterized, including key optimization strategies and solutions to fabrication challenges. By integrating in‐house Ion Beam Figuring and a high uniformity multilayer coating process, the developed DMMs achieve high reflectivity,

Label‐Free Characterization of Lipid Interfaces Using Plasmonic Gold Nanorods as Optically Active Nanosensors

Advanced Optical Materials, EarlyView.
A label‐free plasmonic nanosensor platform is presented based on single gold nanorods for the nanometric characterization of lipid interfaces. By correlating optical scattering signals with membrane packing and refractive index, this approach enables the detection of gel‐to‐fluid transitions in lipid interfaces, offering a robust, high‐resolution ...

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,
