Journal ArticleDOI
Near-field interaction of twisted split-ring resonators
TL;DR: In this paper, the tuning of metamaterials through the relative rotation of the elements about their common axis was observed. And the authors associate this effect with an interplay between the magnetic and electric near-field interactions and verify this by calculations based on the interaction energy between resonators.
Journal ArticleDOI
Phase matching in nonlinear c (2) photonic crystals
TL;DR: A new type of photonic structure is suggested to achieve simultaneous generation of several harmonics and both general analytical results and design parameters for 2D periodically poled LiNbO(3) structures are presented.
Journal ArticleDOI
Azimuthons in nonlocal nonlinear media
TL;DR: It is found that stable azimuthons become possible when the nonlocality parameter exceeds a certain threshold value and, in a sharp contrast to local media, the azimUTHons with N peaks can also exist for N < 2m, where m is the azIMuthon topological charge.
Journal ArticleDOI

TL;DR: This work develops a rigorous theoretical approach for analyzing inelastic scattering of photon pairs in arrays of two-level qubits embedded into a waveguide and identifies the role of different double-excited states in the scattering, such as superradiant, sub Radiant, and twilight states as a product of single-excitation bright and subradiant states.
Journal ArticleDOI
Self-written waveguides in photopolymerizable resins.
TL;DR: An improved analytical model is suggested that describes the growth of single waveguides and the main features of their interaction in photosensitive materials.
