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.

Temperature characteristic of fiber Bragg grating
Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011The basic principle of temperature sensor based on fiber Bragg grating (FBG) is analyzed. A fiber Bragg grating temperature sensor is designed and produced. Using fiber Bragg grating as the sensor, fiber Bragg grating analyzer to demodulation the wavelength shift, the relationship between FBG wavelength shift and temperature is measured.

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 ...
