Dynamic dispersion control with fibre gratings

Dynamic dispersion control with fibre gratings
With the evolution of transmission-systems from point-to-point links to dynamically reconfigurable networks there has developed a need for tunable devices with accurate setting capabilities and stability. When signals are redirected different dispersion accumulates due to the differences in transmission-paths. Furthermore, with the ever increasing bit-rates, differences in signal launch powers and hence the potential for non-linear effects to begin to play their part will have to be considered, and therefore tunability is of increasing importance to either fine tune these dispersion-values or even compensate for some of the non-linear effects. To accommodate these tasks a number of approaches to tune dispersion using Bragg gratings have been demonstrated. Some of these have covered both strain- and temperature- tuning techniques using either single gratings or combinations of multiple gratings. Currently there have been demonstrations of compensation of chromatic dispersion at up to 160Gbit/s.

In this talk we will review and discuss some of these techniques and compare their performance and practicality against each other.

Abstract

With the evolution of transmission-systems from point-to-point links to dynamically reconfigurable networks there has developed a need for tunable devices with accurate setting capabilities and stability. When signals are redirected different dispersion accumulates due to the differences in transmission-paths. Furthermore, with the ever increasing bit-rates, differences in signal launch powers and hence the potential for non-linear effects to begin to play their part will have to be considered, and therefore tunability is of increasing importance to either fine tune these dispersion-values or even compensate for some of the non-linear effects. To accommodate these tasks a number of approaches to tune dispersion using Bragg gratings have been demonstrated. Some of these have covered both strain- and temperature- tuning techniques using either single gratings or combinations of multiple gratings. Currently there have been demonstrations of compensation of chromatic dispersion at up to 160Gbit/s.

In this talk we will review and discuss some of these techniques and compare their performance and practicality against each other.
