Perturbative analysis of generally nonlocal spatial optical solitons [PDF]

open access: yes, 2006
In analogy to a perturbed harmonic oscillator, we calculate the fundamental and some other higher order soliton solutions of the nonlocal nonlinear Schroedinger equation (NNLSE) in the second approximation in the generally nonlocal case.
