Modulational instability in a layered Kerr medium: theory and experiment.

We present the first experimental investigation of modulational instability in a layered Kerr medium. The particularly interesting and appealing feature of our configuration, consisting of alternating glass-air layers, is the piecewise-constant nature of the material properties, which allows a theoretical linear stability analysis leading to a Kronig-Penney equation whose forbidden bands corres...

Modulational instability in nonlocal nonlinear Kerr media.

We study modulational instability (MI) of plane waves in nonlocal nonlinear Kerr media. For a focusing nonlinearity we show that, although the nonlocality tends to suppress MI, it can never remove it completely, irrespective of the particular profile of the nonlocal response function. For a defocusing nonlinearity the stability properties depend sensitively on the response function profile: for...

Generic features of modulational instability in nonlocal Kerr media.

The modulational instability (MI) of plane waves in nonlocal Kerr media is studied for a general response function. Several generic properties are proven mathematically, with emphasis on how new gain bands are formed through a bifurcation process when the degree of nonlocality, sigma, passes certain bifurcation values and how the bandwidth and maximum of each individual gain band depends on sig...

Modulation instability for a relaxational Kerr medium

We investigated on the influence of a temporally dispersive Kerr effect on the modulation instability and the propagation of solitary wave pulse. The modulation instability gain is derived and compared with numerical calculations. The role of nonlinear response time on reshaping the solitary pulse is examined. 2008 Elsevier B.V.

Modulational instability and formation of a nonlinear oscillatory structure in a " focusing " medium

is well known as the universal model for the description of the unstable envelope of strongly dispersive and weakly nonlinear waves. The other interpretation of ( 1 ) is connected with the nonlinear optics of the focusing media (see, e.9., refs. [ 1-3] ). The field of the important physical applications of the NLS equation is extromely wide. To mention just a few: nonlinear deep water waves [4 ...
