Chalcogen Alloy‐Engineered Te2Se/Si Heterojunctions for Low‐Noise Complementary Metal‐Oxide Semiconductor‐Compatible Short‐Wave Infrared Imaging

Advanced Optical Materials, EarlyView.
A Te2Se/Si heterojunction designed through atomistic simulations reduces oxide‐related traps, dark current, and noise compared with pure tellurium devices. This CMOS‐compatible platform enables short‐wave infrared detection and high‐contrast imaging in a 14 × 14 array, highlighting a scalable strategy for robust, low‐noise SWIR photodetectors and image

Inverse‐Designed Superchiral Hot Spot in Dielectric Meta‐Cavity Toward Ultra‐Compact Enantioselective Detection

Advanced Optical Materials, EarlyView.
Linearly polarized incident light with normal incidence creates enhanced optical chirality hotspots on the metasurface. Several orders of magnitude optical chirality enhancement offers a promising route toward highly sensitive, compact chiral spectroscopy.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Force–Displacement Characterization of PNIPAM Microactuators

Advanced Robotics Research, EarlyView.
A method to experimentally establish a force–displacement diagram of poly(N‐isopropyl acrylamide) (PNIPAM) microactuators, printed by 2PP, is presented herein. PNIPAM is a hydrogel whose volume and stiffness change with temperature due to the absorption or release of water.
