AbstractA theory of the optical soliton of self-induced transparency (SIT) in a black phosphorus monolayer (phosphorene) has been developed. Explicit analytical expressions describing the surface soliton in phosphorene and other anisotropic two-dimensional materials are obtained. It is shown that the anisotropic phosphorene conductivity leads to exponential damping of the amplitude of the soliton of the surface wave, which strongly depends on the direction of pulse propagation. The maximum damping of the SIT soliton amplitude takes place in the “armchair” direction of phosphorene.

This paper presents the modulation instability (MI) analysis and the different types of optical soliton solutions of the Triki–Biswas model equation. The aforesaid model equation is the generalization of the derivative nonlinear Schrödinger equation which describes the ultrashort pulse propagation with non-Kerr dispersion. The study is carried out by means of a novel efficient integration scheme. During this work, a sequence of optical solitons is produced that may have an important in optical fiber systems. The results show that the studied model hypothetically has incredibly rich optical soliton solutions. The constraint conditions for valid soliton solutions are also reported. The gained results show that the applied method is efficient, powerful and can be applied to various complex models with the help of representative calculations.
