Reconstruction of fiber grating refractive-index profiles from complex bragg reflection spectra.
Reconstruction of the refractive-index profiles of fiber gratings from their complex Bragg reflection spectra is experimentally demonstrated. The amplitude and phase of the complex reflection spectrum were measured with a balanced Michelson interferometer. By integrating the coupled-mode equations, we built the relationship between the complex coupling coefficient and the complex reflection spe...
متن کاملA Guide to Fiber Bragg Grating Sensors
Optical fiber sensors (OFS) appeared just after the invention of the practical optical fiber by Corning Glass Works in 1970, now Corning Incorporated, that produced the first fiber with losses below 20 dB/km. At the beginning of this era, optical devices such as laser, photodetectors and the optical fibers were very expensive, afforded only by telecom companies to circumvent the old saturated c...
متن کاملFiber Optic Bragg-Grating Sensors
In-fibre Bragg gratings are sensor elements which are photo-written into optical fibre using intense ultra-violet laser beams and have the potential for the measurement of strain/deformation and temperature with applications reported including monitoring of highways, bridges, aerospace components and in chemical and biological sensors. The development of a fiber Bragg grating (FBG) measuring sy...

In this paper, we analyze theoretically and experimentally the performance of fiber Bragg gratings as temperature sensors. These sensors have potential applications in monitoring the temperature in aerospace structures and smart structures. Index Terms Fiber Bragg Gratings, Optical Fibers and Temperature Sensors.
متن کاملCharacterizing femtosecond laser inscribed Bragg grating spectra.
We present numerical modeling based on a combination of the Bidirectional Beam Propagation Method and Finite Element Method that completely describes the wavelength spectra of point by point femtosecond laser inscribed fiber Bragg gratings, showing excellent agreement with experiment. We have investigated the dependence of different spectral parameters such as insertion loss, all dominant cladd...
