Optical vortices in dispersive nonlinear Kerr type media
Lubomir M. Kovachev
The applied method of slowly varying amplitudes of the electrical and magnet vector fields give us the possibility to reduce the nonlinear vector integro-differential wave equation…
Nonlinear Amplitude Maxwell-Dirac Equations. Optical Leptons
Lubomir M. Kovachev
We apply the method of slowly-varying amplitudes of the electrical and magnet fields to integro-differential system of nonlinear Maxwell equations. The equations are reduced to sys…
3D+1 Parametric Bright Vortex Solitons. Optical Mesons
Lubomir M. Kovachev
Using the method of separation of variables, we developed a vector nonparaxial theory from the nonlinear wave equations in strong field approximation of a Kerr media. Investigating…
Three dimensional bright vortex soliton
L. M. Kovachev
Using the method of separation of variables, we developed a vector nonparaxial theory for the nonlinear wave equations in strong field approximation. We found that exact localized…
