Optical fiber sensors based on tapered optical fiber (TOF) structure have attracted a
considerable amount of attention from researchers due to the advantages of simple …

A critical challenge to realize ultra-high sensitivity with optical fiber interferometers for label
free biosensing is to achieve high quality factors (Q-factor) in liquid. In this work a high Q …

This Letter reports a miniature 7-in-1 fiber-optic Raman probe that eliminates the inelastic
background Raman signal from a long-fused silica fiber. Its foremost purpose is to enhance …

The early diagnosis of myocardial infarction can significantly improve the survival rate in
emergency treatment, which is mainly implemented by the immunoassay for myocardial …

A highly sensitive optical fiber temperature sensor with a polydimethylsiloxane (PDMS)-
coated tapered dispersion compensation fiber (DCF) structure is proposed, the structure …

Squamous cell carcinoma antigen (SCCA) is one of the most commonly detected cancer
biomarkers for a variety of cancers. In this paper, a microfiber ring laser biosensor with a …

A fiber ring laser based on a side-polish fiber Mach-Zehnder interferometer (MZI) for
effective improving refractive index (RI) and torsion sensing is proposed and investigated …

An all-single-mode fiber intracavity displacement sensor based on U-shaped single-mode
fiber interferometer (U-SMFI) is demonstrated theoretically and experimentally. The …

Most plasmonic sensors are based on monitoring shifts of the plasmon resonance peak.
Here, we report on a new approach that consists of monitoring nanospectroscopic …

In this article, we demonstrate a phase-demodulated high-order intermodal interference
based on exposed-core microstructure fiber (ECF), and it is applied for low-concentration in …
