Comparative analysis of silica fiber Bragg grating and chalcogenide fiber Bragg grating

Materials Today: Proceedings, 2021
Abstract Sensing performance of silica fiber Bragg grating (FBG) and chalcogenide FBG are compared in presence of apodization functions. The Bessel and Gaussian apodization functions are chosen in this analysis. These fibers are compared on the basis of their sensitivity, detection accuracy, quality parameter and sidelobe suppression ability ...

Fiber Bragg gratings inscribed in nanobore fibers

Optics Letters, 2023
The nanobore fiber (NBF) is a promising nanoscale optofluidic platform due to its long nanochannel and unique optical properties. However, the applications of NBF are only based on its original fiber geometry without extra functionalities so far, compared with various telecom fiber devices, which may limit its wide applications.

Microstructured Fiber Bragg Gratings

Journal of Lightwave Technology, 2009
The first fiber Bragg gratings were accidentally written in a Ge-doped silica fiber using a high power argon-ion laser [Hill 1978]. Following this first evidence of photosensitivity in optical fibers, a huge effort was put into fiber gratings: improving their fabrication (they are now all externally inscribed), obtaining complex profiles, optimizing ...

Periodic waves in fiber Bragg gratings

Physical Review E, 2008
We construct two families of exact periodic solutions to the standard model of fiber Bragg grating (FBG) with Kerr nonlinearity. The solutions are named "sn" and "cn" waves, according to the elliptic functions used in their analytical representation. The sn wave exists only inside the FBG's spectral bandgap, while waves of the cn type may only exist at
