Traveling Bubbles and Vortex Pairs within Symmetric 2D Quantum Droplets
Angel Paredes, Jose Guerra-Carmenate, Jose R. Salgueiro +2
We disclose a class of stable nonlinear traveling waves moving at specific constant velocities within symmetric two-dimensional quantum droplets. We present a comprehensive analysi…
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…
Lattice hyper-solitons in photorrefractive materials
Jose Ramon Salgueiro, Humberto Michinel, Maria I. Rodas-Verde
We show a novel kind of nonlinear waves in two-dimensional photonic lattices. This waves take the form of light clusters that may fill an arbitrary number of lattice sites. We have…
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…
Nonlinear dual-core photonic crystal fiber couplers
Jose R. Salgueiro, Yuri S. Kivshar
We study nonlinear modes of dual-core photonic crystal fiber couplers made of a material with the focusing Kerr nonlinearity. We find numerically the profiles of symmetric, antisym…
Square vortex solitons with a large angular momentum
Humberto Michinel, Jose R. Salgueiro, Maria J. Paz-Alonso
We show the existence of square shaped optical vortices with a large value of the angular momentum hosted in finite size laser beams which propagate in nonlinear media with a cubic…
