Fiber optic grating technology

This paper discusses the different methods of fabricating fiber gratings, the different types of fiber gratings and fiber grating devices, and their connection with laser diodes and fiber lasers. We then discuss the fiber grating as a sensor, its sensitivity to different measurands, methods of decoding the sensor response, multiplexing the sensors, and finally their high temperature limitations. Specific references to the materials presented are very numerous and have been omitted. A short list of review papers on fiber gratings is given at the end of the paper. These review papers have more extensive reference lists for many of the developments covered here.
