| Abstract | ||||
| Chaotic fluctuation of laser output is obtained at a relatively wide range of laser parameters. The dynamical behavior of semiconductor lasers with optical feedback from an external mirror was described by the rate equations modeled by Lang and kobayashi. Some models were numerically analyzed this behavior but in our work we extended the previous results by allowing two reflections, and multiple reflections in the extended cavity. It is found that the chaotic state be very sensitive to the higher order reflections when the reflection coefficient is large. | ||||
