Distributed OTDR-interferometric sensing network with identical ultra-weak fiber Bragg gratings.
Optics Express, 2015 We demonstrate a distributed sensing network with 500 identical ultra-weak fiber Bragg gratings (uwFBGs) in an equal separation of 2m using balanced Michelson interferometer of the phase sensitive optical time domain reflectometry (φ-OTDR) for acoustic ...

Advances in Safe, Flexible, and Stretchable Batteries for Wearable Applications
Advanced Materials Technologies, EarlyView.Unlike previous reviews centered on component‐based deformability, this work highlights safety‐driven design strategies for flexible and stretchable batteries. By integrating material‐level engineering, geometry‐controlled structures, biocompatibility, and self‐protection mechanisms, it establishes a unified framework that connects mechanical ...

Amplitude-squeezed fiber-Bragg-grating solitons [PDF]
Physical Review A, 2004 Quantum fluctuations of optical fiber Bragg grating solitons are investigated numerically by the back-propagation method. It is found for the first time that the bandgap effects of the grating act as a nonlinear filter and cause the soliton to be amplitude squeezed.

Fiber Bragg grating-based linear-cavity fiber laser
Optics Express, 2023 A fiber Bragg grating-based linear-cavity fiber laser is proposed and demonstrated experimentally. A single-mode fiber Bragg grating is used as a wavelength selector in the fundamental mode, and four few-mode fiber Bragg gratings are used to reflect LP01 mode, LP11 mode, LP21 mode and LP02 mode at the same wavelength.
