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 …

In recent years, optical fiber sensors based on multimode interference (MMI) have attracted
increasing interest and developed into various sensors used in many practical applications …

Photonics is a fast and gallo** technology related to both microwave and optics science.
Photonics is a very vast and distinctive field in recent days. Due to the enlarged difficulty of …

The proposed sensing device relies on the self-imaging effect that occurs in a pure silica
multimode fiber (coreless MMF) section of a single-mode–multimode–single-mode (SMS) …

An S-tapered fiber sensor has been realized on the common single-mode fiber by a fusion
splicer. The S fiber taper (SFT) can be considered as a compact fiber Mach-Zehnder …

A fibre-optic strain sensor based on a gourd-shaped joint multimode fibre (MMF)
sandwiched between two single-mode fibres (SMFs) is described both theoretically and …

We demonstrate, for the first time, use of a stretched single mode-graded-index multimode-
single mode fiber (SMF-GIMF-SMF) structure as a saturable absorber (SA) for a passively …

A reflective fiber optic sensor based on multimode interference for the measurement of
refractive index variations in glucose aqueous solutions is proposed. The sensor is …

We carried out a detailed investigation on a compact in-line multimode single-mode
multimode (MSM) fiber structure. Both theoretical modal and experimental setup were …

A novel highly sensitive fiber sensor for transverse load and temperature measurement has
been fabricated by polydimethylsiloxane (PDMS) packaging an S fiber taper (SFT). The …
