Distributed Refractive Index Sensing Based on Etched Ge-Doped SMF in Optical Frequency Domain Reflectometry. [PDF]

Sensors (Basel), 2023
A distributed optical fiber refractive index sensor based on etched Ge-doped SMF in optical frequency domain reflection (OFDR) was proposed and demonstrated. The etched Ge-doped SMF was obtained by only using wet-etching, i.e., hydrofluoric acid solution.

Permittivity-asymmetric qBIC metasurfaces for refractive index sensing. [PDF]

Nanophotonics
Abstract Bound states in the continuum (BICs) provide exceptional light confinement due to their inherent decoupling from radiative channels. Small symmetry breaking transforms BIC into quasi‐BIC (qBIC) that couples to free‐space radiation enabling ultra‐high‐quality‐factor (Q‐factor) resonances desirable for ...
