Review of Scientific Instruments, 1997
Since the discovery of photosensitivity in optical fibers there has been great interest in the fabrication of Bragg gratings within the core of a fiber. The ability to inscribe intracore Bragg gratings in these photosensitive fibers has revolutionized the field of telecommunications and optical fiber based sensor technology.

Fiber Bragg gratings inscribed in nanobore fibers
Optics Letters, 2023The nanobore fiber (NBF) is a promising nanoscale optofluidic platform due to its long nanochannel and unique optical properties. However, the applications of NBF are only based on its original fiber geometry without extra functionalities so far, compared with various telecom fiber devices, which may limit its wide applications.

Magnetically Tunable Fiber Bragg Gratings
Wavelength Division Multiplexing Components, 1999We believe we report the first demonstration of a broad-range (15.7 nm) tuning of fiber Bragg grating using fast, programmable, and latchable magnetic actuation. A key advantage is that the device requires no power except when shifting wavelengths.

Structured Chirped Fiber Bragg Gratings
Journal of Lightwave Technology, 2008In this paper, a theoretical and numerical analysis of novel in-fiber photonic devices based on a structured chirped fiber Bragg gratings (CFBGs) for sensing and communication applications is presented. The investigated structure consists in a CFBG with single or multiple defects obtained by a deep and localized stripping of the cladding layer along ...

Polymer micro-fiber Bragg grating
Optics Letters, 2013Polymer micro-fibers with inscribed Bragg gratings are reported in this Letter. Starting with a single-mode polymer optical fiber and implementing a two-stage tapering process, a 16 μm diameter micro-fiber is fabricated and a Bragg grating is inscribed in it that exhibits a peak reflected wavelength circa 1530 nm.

Tilted fiber Bragg grating sensors
Laser & Photonics Reviews, 2012AbstractOptical fiber gratings have developed into a mature technology with a wide range of applications in various areas, including physical sensing for temperature, strain, acoustic waves and pressure. All of these applications rely on the perturbation of the period or refractive index of a grating inscribed in the fiber core as a transducing ...
