Fiber Bragg gratings in pure-silica polarization-maintaining photonic crystal fiber were photowritten by use of two-photon ultraviolet excitation and characterized for their responses to temperature, axial
Fiber Bragg Grating plays a major role in optical communication and sensing applications in emerging technologies. This paper focuses on the working principle of the Fiber Bragg Grating
They correctly and systematically theorized the light-loss properties for optical fiber, and they identified the right material for such fibers: silica glass with high purity. This discovery earned Kao the Nobel
The wavelength response of the pure-silica-core fiber Bragg grating is less sensitive under the same high-temperature strain as compared with the Ge-doped-core one. The results show a little
The characterization of a fiber Bragg grating in pure-silica-core and Ge-doped-core optical fiber is demonstrated under tensile strain at different temperatures.
Abstract The inscription of fiber Bragg grating (FBG) in a pure-silica multi-core photonic crystal fiber (PCF) using femtosecond laser and phase mask is reported. Three resonant dips are
This Letter presents the characterisation of Si-fibre Bragg grating over the temperature range from 30 to 55°C and with axial strain applied. The results
Abstract We report on fiber Bragg gratings (FBGs) inscribed in pure-silica and Ge-doped photonic crystal fibers (PCFs) with a two-beam interference technique and a femtosecond or excimer
Fiber Bragg gratings are reflective structures in the core of an optical fiber with a periodic or aperiodic perturbation of the effective refractive index.
In recent years, several types of optical fiber hydrogen sensors have been proposed, including those based on interference , micromirror , evanescent field , surface plasmon

Fiber Bragg Grating (FBG) is defined as a passive filter device that consists of a diffraction grating created by periodic modulation of the refractive index in the fiber core, allowing it to reflect specific

Our gratings are written in a hydrogenated microstructured fibre under moderate fluences using a near-field phase mask technique. We describe the spectral and annealing properties of our samples.
The technique of femtosecond laser-induced inscription of fiber Bragg gratings creates a structure in the optical fiber that can be used effectively as a
