The basic techniques for fiber grating fabrication, their characteristics, and the fundamental properties of fiber gratings are described. The many applications of fiber grating technology are tabulated, and some selected applications are briefly described.

The spatial separations of the spots focused on the output plane, corresponding to the FBG wavelengths, are arranged to be larger than the diameter of the GRIN lens so that there is no cross-talk between any two adjacent sensors with this WDM scheme. ...
