Journal ArticleDOI
Focusing and correlation properties of white-light optical vortices.
Vladlen G. Shvedov,Wieslaw Krolikowski,Alexander V. Volyar,Dragomir N. Neshev,Anton S. Desyatnikov,Yuri S. Kivshar +5 more
TL;DR: It is shown that the generated polichromatic vortices are structurally stable, and their correlation properties can be altered by the beam focusing, resulting in changes of the vortex core visibility.
Journal ArticleDOI
Huge enhancement of backward second-harmonic generation with slow light in photonic crystals
TL;DR: In this article, a reliable modal algorithm for describing the light propagation taking into account the vectorial character of the interacting fields as well as the tensorial character of nonlinearity was proposed.
Journal ArticleDOI
Second-harmonic generation in subwavelength graphene waveguides
TL;DR: In this paper, the second-order nonlinear processes can be actualized for interacting plasmonic modes with an effective grating coupler to allow external pumping of the structure with the generated radiation at the double frequency.
Journal ArticleDOI
Multipolar Third-Harmonic Generation in Fishnet Metamaterials
Lei Wang,Alexander S. Shorokhov,Pavel N. Melentiev,Sergey Kruk,Manuel Decker,Christian Helgert,Christian Helgert,Frank Setzpfandt,Frank Setzpfandt,Andrey A. Fedyanin,Yuri S. Kivshar,Dragomir N. Neshev +11 more
TL;DR: In this article, the third harmonic radiated from the fishnet structure is a result of the interference of the electric and magnetic dipoles and the electric quadrupole modes, which provides direct evidence of the importance of higher order multipoles in the nonlinear response of fishnet metamaterials.
Journal ArticleDOI
Scattering of the discrete solitons on the PT-symmetric defects
TL;DR: In this article, the propagation of linear waves and solitons in an array of optical waveguides with an embedded defect created by a pair of waveguide with gain and loss satisfying the so-called parity-time () symmetry condition was studied.
