An in-fiber Mach–Zehnder Interferometer (MZI), based on hollow core fiber (HCF), for
measuring curvature is fabricated and experimentally demonstrated. The sensing part was …

Refractive index (RI) of substance, liquid is an imperative optical measure since it possesses
the optical property of substance and liquid. Efficient and accurate method of determining …

An all-fiber high temperature and refractive index (RI) sensor based on the Michelson
interferometer is proposed and experimentally demonstrated. The sensor probe was …

Problems associated with the disturbance location of asymmetric interferometer disturbance
sensors and 3× 3 coupler based phase demodulation are investigated. It is shown that …

Fiber optic localized surface plasmon resonance (LSPR) sensors have become an effective

In this paper, we develop an alternative all-fiber interferometer, which is based on a
commercial graded-index multimode fiber mismatch spliced between two single-mode …

A tunable multi-wavelength fiber laser is proposed and demonstrated based on two main
elements: an erbium-doped fiber ring cavity and compact intermodal fiber structure. The …

Here we demonstrate an inexpensive, simple, and ultra-sensitive refractive index sensor
based on a tapered tip optical fiber combined with a straightforward image analysis method …

A switchable dual-wavelength thulium-doped all-fiber laser incorporating a fiber tip modal
interferometer (FTMI) is reported. The FTMI relies on the splice joint between a standard …
