“…[12][13][14][15][16] The difference in nature of these two coupled SPP modes arises from the fact that they have different surface charge density distributions. The LRSPP has a charge distribution which is antisymmetric between the top and bottom surfaces (in other words if there is a positive charge density on the top surface there is a corresponding negative charge density on the bottom surface).…”

A NOTE ON VERSIONSThe version presented here may differ from the published version. If citing, you are advised to consult the published version for pagination, volume/issue and date of publication Coupled surface plasmon polaritons on thin metal slabs corrugated on both surfaces A modelling study of the effect of coupled surface plasmon polaritons (SPPs) on the optical response of a thin metal film corrugated on both surfaces is presented. Initially the case of conformally corrugated metal films (the corrugations on each surface are identical and in phase with each other) is considered. Sinusoidal structures, and those having an additional first harmonic, 2k g (where k g is the grating vector) component, are investigated. This 2k g component opens up significant band gaps in the SPP dispersion curves, and also causes anticrossing behavior between the long range SPPs and short range SPPs. It is shown that this anticrossing, and the band gap, have a common explanation. Following this, nonconformally corrugated films are examined, and strongly enhanced resonant transmission is shown to occur, which can be almost independent of the in-plane wave vector. The results presented show that, though the enhanced transmission through hole arrays which has provoked extensive recent investigation is of great interest from a physics viewpoint, other structures which exhibit enhanced transmission may provide more benefits, including higher transmission, for some applications.

“…Judging from this recent literature, it looks like in our experimental geometry the main source of instability might be the multi-stability of the pumped SPP modes on a plane nonlinear interface [20][21][22][23], while the disorder causes phase fluctuations and coherent localization/backscattering phenomena. For example, Shadrivov et al [18] calculated considerably lower onset of the bi-stability of Anderson localized states in lower-dimensional random nonlinear structures, which depends exponentially on the L/l ratio (see Eq.…”

Experimental observation of speckle instability in a two-dimensional disordered medium

Temporal fluctuations of the speckle pattern formed upon backscattering of a laser beam from an interface between gold and nonlinear polymer film have been observed as a function of optical power. The instability can be explained by coupling of laser light to surface plasmons and other guided modes, which experience multiple scattering while propagating in the film along the interface. The speckle pattern produced in this process is extremely sensitive to fluctuations of the scattering potential near the interface.Propagation of coherent waves in disordered media is the topic of considerable current interest. Many experimental situations, such as light propagation in weakly disordered Kerr media [1], the theory of hydrodynamic turbulence [2], the theory of turbulent plasma [3], the mesoscopic theory of interacting electrons in disordered metals [4], etc. can be described by a nonlinear Schrodinger equation in which a field φ(r) propagation in an elastically scattering medium is affected by both the medium potential u(r), and by the nonlinear self-interaction potential βn(r) = β|φ(r)| 2 . While in the linear β = 0 limit the field distribution exhibits speckle (which means that n(r) becomes random, sample specific function of coordinates), it has been shown very recently [4,5] that in the nonlinear case the speckle pattern exhibits instability, and hence temporal fluctuations. The striking feature of this theoretical result is that the

“…While the number of studies on finite-width stripes embedded in nonlinear media is scant, there exists an abundant literature on nonlinear SPs guided by infinitely wide films [12][13][14][15][16][17][18][19][20][21][22][23][24]. Historically, the case of two-dimensional metal films bounded by materials exhibiting a power-dependent refractive index (Kerr nonlinearity) has occupied a central place in these investigations [14][15][16][17][18][19][20].…”

“…Historically, the case of two-dimensional metal films bounded by materials exhibiting a power-dependent refractive index (Kerr nonlinearity) has occupied a central place in these investigations [14][15][16][17][18][19][20]. It was shown that the short-and longrange SPs that exist in the linear regime evolve into stationary nonlinear solutions, which are modes with properties that strongly depend on the power but that do not vary along the propagation direction [15,16].…”

We report on plasmonic waveguides made of a thin metal stripe surrounded on one or both sides by a Kerr nonlinear medium. Using an iterative numerical method, we investigate the stationary long-range plasmons that exist for self-focusing and self-defocusing Kerr-type nonlinearities. The solutions are similar to the wellknown case of infinitely wide nonlinear waveguides-they are strongly power-dependent and can experience symmetry-breaking bifurcations under appropriate conditions.
