Nonlinear dynamics of a delayed optoelectronic feed back with directly modulated semiconductor laser are studied numerically. The effects of changing the bias current of the delayed modulated optoelectronic feedback with small modulation factor producing chaotic outputs from lasers Diode with nonlinear gain reduction in its optimum value range is investigated. The beginning of transition from periodic state to the chaotic state when bias current (δ = 1.01402) was observed. The chaotic dynamics
