Locally pressed fibre Bragg grating pressure sensor [PDF]
, 2006 A spectral-hole created by locally pressing a fibre Bragg grating exhibited a wavelength-shift within the FBG bandwidth. A sensitivity of 74.3pm/(N/mm) was obtained for pressure applied along the slow axis of a high birefringence ...

Quadratic behavior of fiber Bragg grating temperature coefficients [PDF]
, 2004 We describe the characterization of the temperature and strain responses of fiber Bragg grating sensors by use of an interferometric interrogation technique to provide an absolute measurement of the grating wavelength. The fiber Bragg grating temperature

Polarization independent Bragg gratings using tilted subwavelength grating waveguide Bragg gratings
Optics Express, 2023 We propose and experimentally demonstrate a polarization independent subwavelength grating (SWG) waveguide Bragg grating (WBG) by using an SWG waveguide with tilted segments. By optimizing the tilting angle and other geometry parameters, such as the width and the length of the loading segments used to create the BG, we can obtain a zero birefringence ...

Bragg Grating Cavity Design Using Bragg Gratings
International Journal For Multidisciplinary Research, 2023 The aim of the experiment is to design Bragg Grating Cavity design (to show Fabry Perot effects) for High Quality Factor. The basic Bragg Grating design used in this project consists of two identical Bragg Gratings and a cavity between the two Gratings. Bragg devices are first simulated using Transfer Matrix Model (TMM) on MATLAB.

An optical parametric Bragg amplifier on a CMOS chip
Nanophotonics, 2021 We demonstrate a complementary metal–oxide–semiconductor (CMOS)-compatible optical parametric Bragg amplifier on an ultra-silicon-rich nitride chip. The amplifier design incorporates advantageous group index properties in a nonlinear Bragg grating to ...

Temporal analog of Bragg gratings
Optics Letters, 2023 Recently, scalar coupled-wave theory has been employed to analyze a medium with periodic time-varying permittivity, providing simple expressions and, consequently, straightforward insights into the parametric amplification mechanism. Here, we combine such an approach with the Möbius transformation method to investigate the dispersion and optical ...

UV-Writing of a Superstructure Waveguide Bragg Grating in a Planar Polymer Substrate
Sensors, 2017 We report on the fabrication of a superstructure Bragg grating in a planar polymer substrate. Based on a twofold illumination process an integrated waveguide and a superstructure Bragg grating are subsequently written into bulk polymethylmethacrylate by ...

Dynamic strain measurement of hydraulic system pipeline using fibre Bragg grating sensors
Advances in Mechanical Engineering, 2016 Fatigue failure is a serious problem in hydraulic piping systems installed in the machinery and equipment working in harsh operational conditions. To alleviate this problem, health monitoring of pipes can be conducted by measuring and analysing vibration-
