Tapered Fiber Bioprobe Based on U-Shaped Fiber Transmission for Immunoassay [PDF]
In this paper, a tapered fiber bioprobe based on Mach–Zehnder interference (MZI) is proposed. To retain the highly sensitive straight-tapered fiber MZI sensing structure, we designed a U-shaped transmission fiber structure for the collection of optical ...

Optimized Tapered Fiber Decorated by Ag Nanoparticles for Raman Measurement with High Sensitivity [PDF]
A tapered fiber decorated by Ag nanoparticles is prepared as a surface-enhanced Raman scattering (SERS) substrate. There are two key parameters during the preparation process, the fiber cone angle and the density of decorated AgNPs on the fiber tip ...

Optical transmittance degradation in tapered fibers [PDF]
We investigated the cause of optical transmittance degradation in tapered fibers. Degradation commences immediately after fabrication and it eventually reduces the transmittance to almost zero. It is a major problem that limits applications of tapered fibers. We systematically investigated the effect of the dust-particle density and the humidity on the

Vector Bending Sensor Based on Power-Monitored Tapered Few-Mode Multi-Core Fiber [PDF]
We propose a vector bending sensor based on a tapered few-mode multi-core fiber (FM-MCF). A seven-core six-mode fiber is tapered with an optimized taper ratio, enabling bending sensing through power monitoring.
