Fiber Bragg grating (FBG) is defined as a permanent periodic modulation of the refractive index in the core of a single mode optical fiber, typically measuring around 10 mm in length, which serves as a
Download Citation | Strain Measurement with Fiber Bragg Grating Sensors | Fiber Bragg Grating Sensors (FBGS) are gaining increasing attention in the field of experimental stress analysis.
A fiber Bragg grating is a periodic alteration of core refractive index which is formed by exposure of the optical fiber core to a spatially modulated laser light . The formation of refractive index modulation
A variation of the period of the grating inscripted in a fiber optic – induced by mechanical or thermal perturbation – causes a shift of the reflected peak wavelength, due to the related optical path length
The FBG gratings can be used in different applications, such as laser chirp and dispersion management, fiber optic sensing, fiber laser resonators, power spectrum shaping, wavelength selective reflectors,
HistoryTheoryTypes of GratingsGrating StructureManufactureApplicationsSee AlsoExternal LinksThe first in-fiber Bragg grating was demonstrated by Ken Hill in 1978. Initially, the gratings were fabricated using a visible laser propagating along the fiber core. In 1989, Gerald Meltz and colleagues demonstrated the much more flexible transverse holographic inscription technique where the laser illumination came from the side of the fiber.
