A compact, low loss, and highly sensitive optical fiber curvature sensor is presented. The
device consists of a few-millimeter-long piece of seven-core fiber spliced between two single …

We demonstrate a force and temperature sensor consisting of a multicore fiber (MCF)
spliced between two single-mode fibers. Increasing of the sensitivity to applied force is …

A bending sensor is demonstrated using the combination of a mode-selective photonic
lantern (PL) and a multicore fiber. A short section of three-core fiber with strongly coupled …

A simple and low cost fiber laser temperature sensor based on all-fiber single-mode core-
offset structure has been demonstrated. When temperature is applied on the core-offset …

A novel fiber optic temperature sensor based on a liquid-core multimode interference device
is demonstrated. The advantage of such structure is that the thermo-optic coefficient (TOC) of …

In this article, we propose and demonstrate a cascaded interferometers structure based on a
dual-pass Mach–Zehnder interferometer (DP-MZI) and a Sagnac interferometer (SI) for …

An in-line interferometer based on the intermodal coupling of a multicore fiber (MCF) is
proposed and experimentally demonstrated. The in-line interferometer is fabricated by …

In this letter, we proposed and experimentally demonstrated a novel fiber sensing head
based on 45° tilted fiber end for high-temperature measurement. The sensing head was …

A refractive index (RI) insensitive temperature sensor based on specialty triple-clad fiber
(STCF) is proposed. Based on coupling mode theory, the STCF can be equivalent to a rod …

We demonstrate an experimental technique to generate and measure arbitrary
superpositions of core modes in a multi-core fiber. Two spatial light modulators couple the …
