In this report, modeling and experimental results are presented for three fiber Bragg gratings that were fabricated in Newport F-SMF-28 fiber with the direct-write method. The model is based on coupled-mode theory assuming weakly guiding fibers. Optical sensors based on Fiber Bragg Gratings (FBG) are becoming increasingly popular. They are easy to install, immune to electromagnetic interferences and can also be used in highly explosive atmospheres. But just how does a fiber Bragg grating work? Our experts answer this and other questions. One of the particularly useful applications of a direct-write method is for the fabrication of fiber Bragg gratings (FBGs). The. The Bragg grating acts like a mirror which only reflects one very precise wavelength (colour).
