One-Dimensional Bright Spatial Solitons in Logarithmically Nonlinear Electric Media
The bright spatial solitons in logarithmically nonlinear electric media is studied. It is showed that the bright solitons are possible in corresponding nonlinear media. The spatial width for bright solitons is analyzed. It is revealed that the variation of the beam width is inversely proportional to the peak power of the source: beam width dramatically decreases with increasing the power when the peak power is much lower, exhibiting the good nonlinear effects in such case; The variation of beam width is slow and further constant, exhibiting the saturable propterties for logarithmically nonlinear electric media, when the peak power continuously increases.
