Fiber Bragg Grating Production Process
We demonstrate the fabrication of the fiber Bragg grating (FBG) in a self-developed Yb-doped seven-core fiber using two femtosecond laser direct writing methods: a grating array inscription method and a plane-by-plane inscription method. There are actually three established methods available to manufacture a Fiber Bragg Grating. 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 variation. In this article, we will delve into the intricacies of FBG fabrication, exploring the techniques, applications, and future directions of.
