Abstract In this paper a 6-D optoelectronic system consists of a resonant tunneling diode (RTD) driven by an optical injected semiconductor laser (LD) is reported. A stability analysis of the hybrid system is analytically and numerically performed and paramount role of the effective gain coefficient (EGC) is stuck out in the framework of new stability control. As a result, this parameter allows improving the accuracy of the stability study by circumscribing locked and unlocked regions. Besides, a narrow area of stability is pointed up within the sea of unstable points from which a complex fractal attractor so-called infinite-scroll attractor is highligted. Thereby, Simulink shows generation effectiveness of infinite-scroll attractor erratically interpersed by laminar phases. Also dynamics of Lyapunov exponents has confirmed that it refers to a strange fractal attractor. Moreover chaos control is structurally carried out by direct current (DC) polarisation.
