Record type: Conference or Workshop Item (Paper)


Fibre Bragg gratings (FBGs) consist of a periodic modulation of the refractive index along the core of the fibre. This periodicity creates a photonic bandgap and results in strong reflectivity near the Bragg wavelength. The narrow bandwidth and large dispersion of FBGs makes them ideal for linear dispersion compensator and for add/drop filters in WDM systems. In the nonlinear regime Bragg gratings are bistable devices and thus could potentially form the basis of all-optical switches. Recently we have demonstrated three types of nonlinear switching in Bragg gratings: a simple self-induced nonlinear switch, an all-optical AND gate, and a pump induced switch (the optical pushbroom). To understand these switches it is necessary to recall the basic nonlinear properties of Bragg gratings.
