Experimental Study on the Generation of Optoelectronic Based Chaos Dynamics
In this paper, we present the experimental evidence of chaos generation, modulation by means of optoelectronic feedback of semiconductor laser. The output photocurrent of the pin photodiode is amplified and re-injected as a feedback to the semiconductor laser. The injected feedback photocurrent produce chaotic laser output, the chaos distribution depends on amplifying strength. In addition to the changing between different chaotic outputs, the jump between chaotic to periodic was observed depending on the amplifying strength of the feedback signal. The synchronization between two oscillators (chaos generators) has been achieved by uni-directionally coupling.
