The probability distribution of the conductance at the mobility edge
Marc Ruhlander, C. M. Soukoulis
The probability distribution of the conductance p(g) of disordered 2d and 3d systems is calculated by transfer matrix techniques. As expected, p(g) is Gaussian for extended states…
Metal-insulator transitions in anisotropic 2d systems
Marc Ruhlander, C. M. Soukoulis
Several phenomena related to the critical behaviour of non-interacting electrons in a disordered 2d tight-binding system with a magnetic field are studied. Localization lengths, cr…
Parametric localized modes in quadratic nonlinear photonic structures
Andrey A. Sukhorukov, Yuri S. Kivshar, Ole Bang +1
We analyze two-color spatially localized modes formed by parametrically coupled fundamental and second-harmonic fields excited at quadratic (or chi-2) nonlinear interfaces embedded…
Time Dependent Theory for Random Lasers
Xunya Jiang, C. M. Soukoulis
A model to simulate the phenomenon of random lasing is presented. It couples Maxwell's equations with the rate equations of electronic population in a disordered system. Finite dif…
Pulse driven switching in one-dimensional nonlinear photonic band gap materials: a numerical study
E. Lidorikis, C. M. Soukoulis
We examine numerically the time-dependent properties of nonlinear bistable multilayer structures for constant wave illumination. We find that our system exhibits both steady-state…
Gap deformation and classical wave localization in disordered two-dimensional photonic band gap materials
E. Lidorikis, M. M. Sigalas, C. M. Soukoulis +1
By using two ab initio numerical methods we study the effects that disorder has on the spectral gaps and on wave localization in two-dimensional photonic band gap materials. We fin…
