A singlemode-multimode-singlemode (SMS) fiber structure consists of a short section of
multimode fiber fusion-spliced between two SMS fibers. The mechanism underpinning the …

During the last decades, both governments and companies have been committed to the
continuous checking of biological parameters, which can prevent extra costs to …

We propose and demonstrate a thinned fiber based Mach-Zehnder interferometer for multi-
purpose sensing applications. The sensor head is formed by all-fiber in-line singlemode …

In recent years, metamaterials and metasurfaces have prospered in many fields of “science
and technology,” covering the entire electromagnetic spectrum. Metasurface devices …

An optical fiber magnetic field sensor based on the single-mode–multimode–single-mode
(SMS) structure and magnetic fluid (MF) is proposed and demonstrated. By using a piece of …

We propose and experimentally demonstrate an enhanced evanescent field fiber
refractometer based on a tapered multimode fiber sandwiched between two single-mode …

Magnetic field sensing based on magnetic fluid (MF) and a singlemode–multimode–
singlemode (SMS) fiber structure is proposed. The sensitivity of the proposed sensing …

We demonstrate refractive index sensors based on single mode tapered fiber and its
application as a biosensor. We utilize this tapered fiber optic biosensor, operating at 1550 …

An ultra-high sensitivity label-free optical fiber biosensor for inactivated Staphylococcus
aureus (S. aureus) detection is proposed and investigated in this study, with additional …

We review fiber-based multimode interference (MMI) devices with a particular focus on
optical fiber-based sensing applications. The present review complements a recently …
