High chaotic spiking rate using mach-Zehnder modulator

الملخص EN

We report experimentally the generation of spiking in semiconductor laser (SL) with an ac-coupled optoelectronic feedback by using nonlinear device Mach-Zehnder modulator (MZM) .

This study is considered in conditional parameter when the DC bias voltage of Mach-Zehnder Modulator is varied .

By changing the control parameter , time series , the corresponding Fast Fourier Transform FFT and attractor have been measured .

To investigate chaotic evolutions ( history of chaos ) for the change of control parameter , the bifurcation diagram is extracted .
