Dynamic counterpropagating vector solitons in saturable self-focusing media.
We display rich spatial and temporal dynamics of light fields counterpropagating in a saturable self-focusing medium numerically, and analyze instabilities that counterpropagating solitons experience. An expression for the maximum length that the medium must not exceed for the solitons to be stable is derived and connected to the coupling strength of beam interaction. The instability can lead t...
متن کاملSelf-Trapping of “Necklace” Beams in Self-Focusing Kerr Media
Solitons in Kerr media are the most well-studied solitons in nature. The reason for that is twofold. First, the Kerr nonlinearity can be found in many systems: It represents a weak symmetric anharmonicity, which is equivalent to a weak saturation in a simple harmonic oscillator. For electromagnetic waves propagating in a weakly nonlinear centrosymmetric dielectric media, the Kerr nonlinearity m...
متن کاملSelf-Focusing Dynamics of Coupled Optical Beams
We theoretically and experimentally investigate the mutual collapse dynamics of two spatially separated optical beams in a Kerr medium. Depending on the initial power, beam separation, and the relative phase, we observe repulsion or attraction, which in the latter case reveals a sharp transition to a single collapsing beam. This transition to fusion of the beams is accompanied by an increase in...
متن کاملSelf-focusing and self-trapping of optical beams upon photopolymerization.
We demonstrate theoretically and experimentally that optical beams are self-focused and self-trapped upon initiating photopolymerization. This unique nonlinear optical phenomenon is dependent on the optical exposure and produces permanent index-of-refraction changes larger than 0.04. The resulting nonlinear wave equation is shown to be nonlocal in time and displays self-trapped solutions only f...
متن کاملSmall-Scale Self-Focusing Effects in Tapered Optical Beams
This memo presents a simple analysis of small-scale self focusing or filamentation effects in strongly diverging or converging optical beams (“tapered beams”) propagating in nonlinear or saturable optical media. In contrast to the collimated beam case where the nonlinear perturbations can be modelled as uniformly spaced periodic ripples, the nonlinear phase and amplitude ripples in the tapered-...
