Fiber Bragg Grating Surface Metallization
A two-step method for metallization in-fiber Bragg grating was developed in this paper, the aim is prepare to embed the fiber sensor in metal. In this study, the fiber Bragg grating (FBG) was metallized with a nickel coat using an electroless-electro plating method. Under the optimum conditions, the surface of chemical plating and electroplating coat are smooth and compact, there is not any visible defect in the cross-section.

Margin on both sides of the grating fiber
For a diffraction grating, the relationship between the grating spacing (i.e., the distance between adjacent grating grooves or slits), the angle of the wave (light) incidence to the grating, and the diffracted wave from the grating is known as the grating equation. Like many other optical formulas, the grating equation can be derived by using the Huygens–Fresnel principle, stating that each point on a w. OverviewIn, a diffraction grating is a with a periodic structure of appropriate scale so as to light, or another type of, into several beams traveling in different directions (i.e., different diff. The wavelength dependence in the grating equation shows that the grating separates an incident beam into its constituent wavelength components at different angles, i.e., it is angular. Each wavel. Surface-relief (SR) gratings are named due to its surface structure of depressions (low relief) and elevations (high relief). Originally, high-resolution gratings were ruled by high-quality whose constructio.
