Abstract
It is well known what solitons can be excited in wide range of nonlinear media due to the balance of dispersive and nonlinear effects [1]. The properties of solitons in the media with third-order nonlinearity were studied very intensive. In particular, the phenomenon of slow and immobile solitons forming near the bounds of nontransmission bands in the medium with complex dispersion was discovered and studied theoretically and numerically in [2–4]. This phenomenon is based on the bound frequency shift due to self-action effects. The input signal on forbidden frequencies splits into slow non-dumping solitons. This phenomenon was named “nonlinear tunneling” [2]. Solitons that propagate in forbidden bands are known as “gap solitons”.
