Solitons in Nonlocal Media

2.5 Theory of Nonlinear Optical Propagation in NLC
Figure 2.16: Numerically computed soliton profile u(x,t = 0) versus x − a/2 (blue line)
and corresponding best-fit with a Gaussian (red line) for P = 0.1 (a), 1 (b), 2 (c) and 3mW
(d), at λ = 633nm. (e) Soliton existence curve in the plane waist-power at λ = 633nm
(red) and λ = 1064nm (black). Waist of the Gaussian which best-fits the actual soliton
shape is taken into account. Plot of maximum u (f) and θ (g) versus soliton power; red
and black curves correspond to λ = 633 and 1064nm, respectively.
Figure 2.17: Contour plots of numerically computed intensity profile |u| 2 (a) and director
angle θ (b) in the space xts for P = 1mW and λ = 633nm, when the input beam is solution
of eqs. (2.19)-(2.20).
