Abstract

Very narrow, with the width smaller than a wavelength, solitons in (1+1)-dimensional and (2+1)-dimensional versions of cubic–quintic and full saturable models are studied, starting with the full system of the Maxwell’s equations rather than the paraxial (nonlinear Schrödinger) approximation. For the solitons with both TE and TM polarizations it is shown that there always exists a finite minimum width, and the solitons cease to exist at a critical value of the propagation constant, at which their width diverges. Full similarity of the results obtained for both nonlinearities suggests that the same general conclusions apply to narrow solitons in any non-Kerr model.
