Semiclassical limit of the scattering transform for the focusing Nonlinear Schr\" odinger Equation
Alexander Tovbis, Stephanos Venakides
The semiclassical limit of the focusing Nonlinear (cubic) Schr\" odinger Equation (NLS) corresponds to the singularly perturbed Zakharov Shabat (ZS) system that defines the direct…
Fano-Type Resonance of Waves in Periodic Slabs
Natalia Ptitsyna, Stephen P. Shipman, Stephanos Venakides
We investigate Fano-type anomalous transmission of energy of plane waves across lossless slab scatterers with periodic structure in the presence of non-robust guided modes. Our app…
Determinant form of modulation equations for the semiclassical focusing Nonlinear Schr\" odinger equation
Alexander Tovbis, Stephanos Venakides
We derive a determinant formula for the WKB exponential of singularly perturbed Zakharov-Shabat system that corresponds to the semiclassical (zero dispersion) limit of the focusing…
Accurate description of optical precursors and their relation to weak-field coherent optical transients
William R. LeFew, Stephanos Venakides, Daniel J. Gauthier
We study theoretically the propagation of a step-modulated optical field as it passes through a dispersive dielectric made up of a dilute collection of oscillators characterized by…
