Switching of optical vortices in nonlinear annular couplers
Jose R. Salgueiro, Yuri S. Kivshar
We suggest an annular waveguide coupler for switching the angular momentum of light. We study linear and nonlinear coupling of both power and momentum of an optical vortex beam lau…
Discrete Nonlinear Breathing Modes in Carbon Nanotubes
Alexander V. Savin, Yuri S. Kivshar
We study large-amplitude oscillations of carbon nanotubes with chiralities and and predict the existence of localized nonlinear modes in the form of {\em discrete b…
Incoherent multi-gap optical solitons in nonlinear photonic lattices
Kristian Motzek, Andrey A. Sukhorukov, Friedemann Kaiser +1
We demonstrate numerically that partially incoherent light can be trapped in the spectral band gaps of a photonic lattice, creating partially incoherent multi-component spatial opt…
Spatial vector solitons in nonlinear photonic crystal fibers
Jose R. Salgueiro, Yuri S. Kivshar, Dmitry E. Pelinovsky +2
We study spatial vector solitons in a photonic crystal fiber (PCF) made of a material with the focusing Kerr nonlinearity. We show that such two-component localized nonlinear waves…
Optical Vortices and Vortex Solitons
Anton S. Desyatnikov, Lluis Torner, Yuri S. Kivshar
Optical vortices are phase singularities nested in electromagnetic waves that constitute a fascinating source of phenomena in the physics of light and display deep similarities to…
Coherence controlled soliton interactions
Ting-Sen Ku, Ming-Feng Shih, Andrey A. Sukhorukov +1
We demonstrate theoretically and subsequently observe in experiment a novel type of soliton interaction when a pair of closely spaced spatial optical solitons as a whole is made pa…
