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 …

Fibers are undeniably one of the most successful solid-state active media for lasers to date.
The reason is to be found in the thin elongated geometry of the fiber which, in contrast to …

In this Letter, we demonstrate a compellingly simple directional bending sensor based on
multicore optical fibers (MCF). The device operates in reflection mode and consists of a short …

We present a new technique allowing the fabrication of large modal count photonic lanterns
for space-division multiplexing applications. We demonstrate mode-selective photonic …

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 …

Sensors based on Bragg gratings inscribed in conventional single mode fibers are
expensive due to the need of a sophisticated, but low-speed, interrogation system. As an …

We demonstrate a compact and versatile interferometric vibration sensor that operates in
reflection mode. To build the device, a short segment of symmetric strongly coupled …

In this paper, a highly sensitive vector curvature sensor based on two juxtaposed fiber
Michelson interferometers (MI) with Vernier-like effect has been proposed and verified …

A novel low-cost, compact, assembly-free and sensitive optical fiber curvature sensor is
presented. This device consists of an off-axis positive refractive index modified zone …

A novel optical fiber grating vector bending sensor head is demonstrated. The sensor head
is composed by two cascaded 6° tilted long period fiber gratings, which are separated by a …
