Controlling chaos of vertical-cavity surface-emitting lasers with optical feedback

The authors propose a new compound cavity model with optical feedback for study the nonlinear dynamic behavior of VCSEL. The results show that system can be controlled to its fixed point, periodic orbits by using modulation parameters. In addition, the stable range be obtained and indicate the introduction of external reflectivity enhances chaotic characteristics. As increase of the external mirror reflectivity the CW state become unstable and the output power exhibit single period oscillation, higher order bifurcation, eventually leading to chaos.
