Advanced fibre Bragg gratings and where they are going

Abstract

Bragg gratings in optical fibre waveguides have now been around for nearly 25 years and they were soon after being realised identified as one of the most significant fibre-optic inventions with potentials in a wide variety of areas among telecommunications equivalent to that of the erbium doped fibre amplifier. Following their creation a plurality of infibre functions were thought possible with low or no insertion-loss. Although fabrication and control of vital grating parameters was limited in the early stages of their life, initially a number of filtering functions were identified for obvious demonstrations. It soon became apparent though that not just standard filtering manipulation was possible. Identifying the true potential of the devices has let to considerable effort being concentrated on their full exploitation implying building an infrastructure supported by theoretical design [2] and manufacturing techniques [3,4] around them. These techniques combined have let to a scenario where currently it is the imagination more than the actual design and manufacturing capabilities that imposes a limitation to what is being demonstrated.
We will in this presentation discuss and highlight some of the most recent advances in Bragg grating devices and applications in advanced components. In particular we will show examples of the latest in Bragg gratings for dispersion-control, short pulse manipulation and advanced filtering applications and speculate into what the future holds for these unique devices.
