INFLUENCES OF THE GAIN COEFFICIENT ON THE NONLINEAR OSCILLATOR’S DYNAMICAL REGIMES OF MACH-ZEHNDER MODULATOR MZM WITH OPTOELECTRONIC FEEDBACK
In this research we have modeled the Mach-Zehnder Modulator MZM with optoelectronic feedback OEF as optoelectronic oscillator OEO. The model is based on the Integro-Differential equation, which includes nonlinear effects from MZM device with time delay feedback arise from optoelectronic feedback OEF. Numerical simulation of our OEO model demonstrated wide regimes of complex oscillations, ranged from period one, period doubling, mixed mode, quasi-period and chaotic oscillations, that is with increasing the value of the linear gain coefficient. This effect was verified by the bifurcation diagram of maxima values of RF-voltages versus control parameter which in this case is the linear gain coefficient value, which depicted the route to chaos of OEO system.
