The aim of this paper is to provide a comprehensive review of mode-division and spatial-
division optical fiber sensors, mainly encompassing interferometers and advanced fiber …

In this paper, a review of multicore fiber interferometric sensors is given. Due to the
specificity of fiber structure, ie, multiple cores integrated into only one fiber cladding …

In this work, we present a supermode interferometer for biosensing application. The
interferometer was fabricated with a segment of a seven-core fiber fusion-spliced to a …

We report on a compact, highly sensitive all-fiber accelerometer suitable for low frequency
and low amplitude vibration sensing. The sensing elements in the device are two short …

We propose and demonstrate a compact and simple vector bending sensor capable of
distinguishing any direction and amplitude with high accuracy. The sensor consists of a …

We propose a temperature sensor, which consists of a composite optical waveguide (COW)
sandwiched between two single mode fibers (SMFs). The COW is formed by side polishing a …

In this work, we report on a twin-core fiber sensor system that provides improved spectral
efficiency, allows for multiplexing and gives low level of crosstalk. Pieces of the referred …

In this Letter, a long-range optical fiber displacement sensor based on an extrinsic Fabry–
Perot interferometer (EFPI) built with a strongly coupled multicore fiber (SCMCF) is proposed …

In this paper, we report on a multicore fiber-based (MCF) temperature sensor that operates
in a wide thermal range and that is robustly packaged to withstand harsh environments. To …

An in-line, highly sensitive refractive index (RI) sensor based on a tapered multicore fiber
(MCF) structure sandwiched between two single-mode fibers is proposed and …
