Considerations for producing single-pulse fiber Bragg gratings

The discussion of Bragg fiber gratings (FBGs) has expanded sharply in the last six years. FBGs were given versatility by the results at the United Technology Research Center when the technique of side-writing was pioneered (1989), which made the Bragg wavelength independent of the writing laser. The promise of economical production of these devices was advanced by the generation of FBGs with a single laser pulse at the Naval Research Laboratory (1992), and this result was expanded by the University of Southhampton in achieving saturated reflectivity with a single-pulse. The basis for manufacturing these excitingly versatile devices is near the point of supporting a new area of applications and industry. The intent of this article is to briefly discuss the conditions and requirements for the practical production of FBGs in support of the technology of distributed sensing.
