Self-focusing instability and chaotic behavior of nonlinear optical waves guided by dielectric slab structures.
The propagation of nonlinear optical waves guided by a nonlinear thin film bounded by two linear claddings is examined numerically. Numerical results for the propagation constant versus the propagation axis indicate that for higher-order modes the transition from periodic behavior to chaos through period doubling is observed as the guided-wave power increases, whereas for the fundamental mode an extremely stable self-focusing propagation is possible.
