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,

Dark‐State Guided‐Mode Resonance Sensors: Engineering Miniature Sensing Platforms

Advanced Optical Materials, EarlyView.
This research introduces compact guided‐mode resonance sensing using Gaussian‐beam‐induced symmetry breaking to excite dark states. The method generates high‐quality resonance signals in a small area, demonstrating a sensor with 128 micro‐cells and 200 nm RIU−1 sensitivity, showing potential for lab‐on‐chip and biosensing applications.

Wrinkle‐Template Confinement of Kinetically Arrested Cellulose Nanocrystals for Sustainable Large Scale Reflection Gratings

Advanced Optical Materials, EarlyView.
Self‐supported all‐cellulose reflective gratings are fabricated from cellulose nanocrystal dispersions via a confinement printing process. Taking advantage of the reduced fluidity of concentrated, kinetically arrested cellulose nanocrystal dispersions, line arrays can be successfully transferred to dried CNC films.
