Rock bolts are the devices that used to reinforce the rock masses in mining tunnels and
underground excavation structures. The loading level of the rock bolt indicates the …

We report a graphene-assisted all-optical control of a fiber Bragg grating (FBG), which
enables in-fiber optical bistability and switching. With an optical pump, a micro-FBG …

An innovative functionalization method allowing to greatly increase the Faraday effect of
microstructured silica-based optical fibers is described. This method relies on the coating of …

A functionalized microstructured silica-based optical fiber, displaying significant magneto-
optical effects in the-band telecommunication wavelength (1530–1565 nm) has been …

We have demonstrated novel concept of utilizing the photomechanical actuation in carbon
nanotubes (CNTs) to tune and reversibly switch the Bragg wavelength. When fiber Bragg …

Ultrafast lasers with tunable capabilities of pulse duration and spectrum have widespread
applications in telecommunication, spectroscopy, and nonlinear optical bio-imaging …

A critical first step to many surgical procedures is locating and gaining access to a patients
vascular system. Vascular access allows the deployment of other surgical instruments and …

To verify the feasibility of magnetic field sensing based on the interaction between
evanescent waves and magnetic thin films, we have investigated the polar magneto-optical …

A magnetic field sensor using a non-adiabatic tapered optical fiber (NATOF) interacting with
magnetic fluid (MF) nanoparticles is proposed and experimentally demonstrated. The …
