In this paper, the (2 + 1)-dimensional coupled higher-order nonlinear Schrödinger equations are under investigation. The mixed-type vector solitons are derived via Hirota method. The interactions are analyzed graphically mainly on x–t and x–y planes. Moreover, a high intensity pulse, combined solitary waves and bound state solitons are discovered during the interactions. These results are available in optical fiber communication systems.
