Microcone Array‐Mediated Distance Tuning for Photonic Nanojet‐Amplified SERS

Advanced Optical Materials, EarlyView.
A tunable microcone array platform provides precise vertical gap control between dielectric microspheres and a SERS‐active surface. This structural regulation aligns the photonic nanojet focal point with plasmonic hotspots, delivering a 15‐fold optical signal enhancement.

Strong Coupling in all‐Polymer Planar Microcavities

Advanced Optical Materials, EarlyView.
Strong Coupling has been achieved in an all‐polymer microcavity with dielectric contrast Δn = 0.33 doped with TDBC. A Rabi splitting of 39 meV has been measured opening novel perspectives for polymer photonics. ABSTRACT In this work, strong coupling effect is observed in all‐polymer planar microcavities incorporating TDBC J‐aggregates dispersed into ...

A State‐Adaptive Koopman Control Framework for Real‐Time Deformable Tool Manipulation in Robotic Environmental Swabbing

Advanced Robotics Research, EarlyView.
This work presents a state‐adaptive Koopman linear quadratic regulator framework for real‐time manipulation of a deformable swab tool in robotic environmental sampling. By combining Koopman linearization, tactile sensing, and centroid‐based force regulation, the system maintains stable contact forces and high coverage across flat and inclined surfaces.
