Abstract:
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.

02:18X-ray Crystallography
The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

01:07Propagation of Waves
When a wave propagates from one medium to another, part of it may get reflected in the first medium, and part of it may get transmitted to the second medium. In such a case, the interface of the two mediums can be considered as a boundary that is neither fixed nor free.
Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...
