High-intensity pulse propagation in uniform gratings and grating superstructures

We briefly review our recent nonlinear propagation experiments in optical fiber Bragg gratings (FBGs). These experiments demonstrate nonlinear pulse compression, and pulse shaping, and also show how a train of pulses may be generated from a single input pulse. Our results also demonstrate the existence of Bragg grating solitons, solitons which exist by balancing of the nonlinearity of the glass and the dispersion of the grating.
