Vector pulsing soliton of self-induced transparency in waveguide

•An optical vector pulsing soliton in a planar waveguide is presented.•Explicit form of the optical vector pulsing soliton are obtained.•The vector pulsing soliton and the soliton have different parameters and profiles.

A theory of an optical resonance vector pulsing soliton in waveguide is developed. A thin transition layer containing semiconductor quantum dots forms the boundary between the waveguide and one of the connected media. Analytical and numerical solutions for the optical vector pulsing soliton in waveguide are obtained. The vector pulsing soliton in the presence of excitonic and bi-excitonic excitations is compared with the soliton for waveguide TM-modes with parameters that can be used in modern optical experiments. It is shown that these nonlinear waves have significantly different parameters and shapes.
