Abstract

The dynamics of chaotic behavior of semiconductor laser diode with optical feedback from single mode fiber loop mirror has been experimentally studied. In the represented configuration the feedback strength was constant while the control parameter with laser injection current was variable, we found a wide range of optical intensity oscillation dynamics such as limit cycles, quasiperiodic and chaos oscillations. These dynamics were analyzed by time series and their extracted FFT power spectrums, phase diagrams (attractors), inter-spike intervals (ISI), these measurements enhanced by bifurcation diagram which clarified the chaotic regimes. Efficient bandwidth of chaotic signals has been calculated and observed to be increased with injection current. The complexity of chaotic system was measured by Shannon’s entropy function.
