Orbital angular momentum beam instabilities in engineered nonlinear colloidal media
Jingbo Sun, Salih Z. Silahli, Wiktor Walasik +3
In this letter, we experimentally demonstrate the evolution of the optical vortex beams of different topological charges propagating in engineered nano-colloidal suspension of nega…
Trajectories and orbital angular momentum of necklace beams in nonlinear colloidal suspensions
Wiktor Walasik, Salih Z. Silahli, Natalia M. Litchinitser
Recently, we have predicted that the modulation instability of optical vortex solitons propagating in nonlinear colloidal suspensions with exponential saturable nonlinearity leads…
Modulation instability of structured-light beams in negative-index metamaterials
Salih Z. Silahli, Wiktor Walasik, Natalia M. Litchinitser
One of the most fundamental properties of isotropic negative-index metamaterials, namely opposite directionality of the Poynting vector and the wavevector, enable many novel linear…
Necklace Beam Generation in Nonlinear Colloidal Engineered Media
Salih Z. Silahli, Wiktor Walasik, Natalia M. Litchinitser
Modulational instability is a phenomenon that reveals itself as the exponential growth of weak perturbations in the presence of an intense pump beam propagating in a nonlinear medi…
