Nonlinear propagation in superstructure Bragg gratings.
The existence of solitary waves in superstructure Bragg gratings is experimentally demonstrated, confirming theoretical predictions. We observe nonlinear compression as a result of a combination of the negative dispersion of the grating and the nonlinear phase shift associated with the pulse intensity. We also demonstrate that, in a superstructure Bragg grating, the dispersion is continuously tunable from normal to anomalous, which allows us to manipulate the shape of the transmitted pulse.
