Abstract

In this paper, temporal and spectral characteristics of uniform nonlinear fiber Bragg gratings (FBG) are investigated in detail using numerical solutions of nonlinear coupled mode equations. The acquired data are considered in terms of using nonlinear FBGs as wavelength converters and all-optical on-off switches in WDM optical networks. The numerical experiments are focused on transmission properties of FBGs based on nonlinear chalcogenide glasses which are suitable candidates due to their strong third-order optical nonlinearities.
