We review the current status of mode-division multiplexing (MDM) techniques in fibers and
on chips. Three system applications are introduced, including quasi-single mode …

We propose and demonstrate a novel curvature and temperature sensor based on an off-
axis small-period long-period fiber grating (SP-LPG) which is inscribed in a single mode …

Multi-parameter sensing technology plays an important role in structural health monitoring.
In this paper, a novel FBG sensor with a pendulum structure for simultaneous measurement …

In this paper, the hollow core Bragg fiber (HCBF)-based sensor based on anti-resonant
reflecting optical waveguide (ARROW) model is proposed and experimentally demonstrated …

An integrated structure in the original single mode fiber (SMF) which can measure curvature
and temperature simultaneously, is proposed and demonstrated. The key components of the …

The development of few-mode fiber (FMF) has found numerous interesting applications in
optical sensing. Given the remarkable capabilities of FMF, optical sensors of novel …

With the rapid development of optical fiber sensor in physical measurement, it is of practical
significant to realize multi-parameter measurement. In this work, we proposed and …

The tilted fiber grating (TFG) is a special grating whose grating planes are slanted or blazed
relative to the fiber axis. These tilts in the planes break the cylindrical symmetry of the fiber …
