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 ...

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 ...

Fiber Bragg Gratings in Industrial Sensing
Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013The tutorial is based on technical experiences obtained during development and numerous practical industry deployments of fiber Bragg grating (FBG) sensors and sensor systems. Technical means will be analyzed, which make FBG to an attractive sensing solution: draw tower Bragg grating technology, sensor-specific fiber coatings, sensor packaging.

SPIE Proceedings, 2012
A low cost, highly accurate and light intensity-independent sensor system for the analysis of fiber Bragg grating signals based on fiber Bragg gratings in the detection unit is presented. The setup is based on two fiber Bragg gratings used in reflection to analyse one sensing fiber Bragg grating.

Bragg gratings in air–silica structured fibers
Optics Letters, 2003We report on grating writing in air-silica structured optical fibers with pure silica cores by use of two-photon absorption at 193 nm. A decrease in propagation loss with irradiation was observed. The characteristic growth curves were obtained.

Ultrashort bragg soliton in a fiber bragg grating
Optics Communications, 2002The propagation of a nonlinear ultrashort pulse in a photonic bandgap structure is investigated by using the finite-difference time-domain method. The simulation results show that an ultrashort pulse near the bandgap edge can propagate through a nonlinear fiber Bragg grating, even if the broadband spectrum of this ultrashort pulse overlaps the whole ...

Bragg gratings in multimode fiber
SPIE Proceedings, 2004Recently, multimode fiber (MMF) and components based on MMF have attracted much attention due to their potential applications in future optical access networks. Fiber Bragg gratings (FBGs) are considered to be key components in both telecommunication and sensing applications.
