Abstract: Response time series of nonlinear optoelectronic delay feedback system is numerical analyzed. Broadband pass filter is inserted in feedback loop of model. Mathematical model of nonlinear optoelectronic delay feedback system is set up. Two routes to chaos are numerical analyzed by adjusting parameters of system. At specific φ, under condition of low feedback gain, fast square wave signal or slow cycle oscillation signal is observed. With increase of feedback gain, more complex periodic signal or chaos breather phenomenon is appeared. At higher feedback gain, output of system is from different dynamic regimes into chaos.

Key words: optoelectronic delay feedback system, chaos, dynamic property, nonlinear
