Journal ArticleDOI
Multipolar second-harmonic generation by Mie-resonant dielectric nanoparticles
TL;DR: By combining analytical and numerical approaches, the authors studied resonantly enhanced second-harmonic generation by individual high-index dielectric nanoparticles made of centrosymmetric materials considering both bulk and surface nonlinearities.
Journal ArticleDOI
Giant lamb shift in photonic crystals.
TL;DR: The photonic-crystal environment can lead to very large values of the Lamb shift, as compared to the case of vacuum, and the position-dependent Lamb shift should extend from a single level to a miniband for an assembly of atoms with random distribution in space, similar to the velocity-dependent Doppler effect in atomic/molecular gases.
Journal ArticleDOI
Dipole azimuthons and vortex charge flipping in nematic liquid crystals.
TL;DR: Self-trapped laser beams carrying phase singularities in nematic liquid crystals are demonstrated and the astigmatic transformation of vortex beams into spiraling dipole azimuthons accompanied by power-dependent charge-flipping of the on-axis phase singularity is observed.
Journal ArticleDOI
Optical gap solitons in nonresonant quadratic media.
TL;DR: In this article, the authors demonstrate the role of optical rectification in the theory of nonlinear wave propagation in quadratically nonlinear optical media and derive a novel physical model for gap solitons in nonlinear Bragg gratings.
Journal ArticleDOI
Vector vortex solitons in nematic liquid crystals.
TL;DR: It is demonstrated that the nonlocal, nonlinear response can dramatically enhance the field coupling leading to the stabilization of the vortex beam when the amplitude of the second beam exceeds some threshold value.
