| Summary: | This paper addresses theoretically generating the chaotic signals by using semiconductor laser diode of 1550 nm with optical feedback. The performance of a semiconductor laser subjected to a delay optical feedback was investigated using rate equations that describe the temporal variation of photon density, carrier density, and the phase of the lasing field. The simulation results show how semiconductor lasers are sensitive to external optical perturbations and how rich chaotic signal with large information can be generated with controlled optical feedback. |
