Linear and Nonlinear Wave Dynamics in Amorphous Photonic Lattices, Bloch’s theorem. Indeed, the free-electron approximation seems to imply that Bragg scattering in periodic potentials is a necessary condition for the formation of a band-gap. But this is obviously untrue: looking through a window reveals that glassy silica (SiO.), although possessing no order at al

Spatial Beam Dynamics Mediated by Hybrid Nonlinearity,ng and self-defocusing nonlinearities in the same material under identical conditions. Such hybrid nonlinearity is established in a nonconventionally biased photorefractive crystal, which offers enhanced anisotropy and nonlocality, leading to a variety of unusual nonlinear beam dynamics in both cont

Spatially Dispersive Shock Waves in Nonlinear Optics,tion so that wave spreading becomes intensity-dependent. The mechanism of this spreading follows naturally from a hydrodynamic description of light flow, in which wave steepening from phase gradients allows faster parts of a beam to overtake slower parts. Scaling relationships are developed for this

The Dawn of Ultrafast Nonlinear Optics in the Terahertz Regime,THz waves cover the region from 100 GHz to 20 THz, thus bridging the gap between microwaves and infrared light. Physically, 1 THz is equivalent to a wavelength of 300 μm in vacuum, to 33.3 cm. in terms of wave numbers, to a photon energy of 4 meV, or to a temperature of 48 K. THz waves have the abil
