ABSTRACT

In this paper, controlling high speed chaos in an optoelectronic device is developed. In this device, a Mach–Zehnder interferometer is used as the source of the nonlinearity and a semiconductor laser as a current to optical frequency converter. The nonlinearity of the interferometer coupled with the delay in the feedback loop combine to produce a range of steady-state, periodic, and chaotic behavior. Our focus is on the design and analysis of a feedback strength control that allows the control of the high dimensional chaotic oscillations generated with the device. The main idea of the proposed control method is to adjust the parameter perturbations for a relatively small time period in order to stabilize the desired unstable periodic orbit and obtain an attracting time-periodic motion.     

Keywords: Chaos, optoelectronic device, unstable periodic orbit, feedback control.
