Synchronization and optical communications by the chaos modulation technique using quantum dot lasers with t-type optical feedback
We investigate the synchronization and optical communication processes using quantum dots lasers under the influence of external T-type optical feedback. The dynamical behavior of a single mode laser is studied in terms of the Bloch equation model. Appropriate conditions for chaotic behavior and syn...

| Sumario: | We investigate the synchronization and optical communication processes using quantum dots lasers under the influence of external T-type optical feedback. The dynamical behavior of a single mode laser is studied in terms of the Bloch equation model. Appropriate conditions for chaotic behavior and synchronizations are fond. Under these conditions, the chaos modulation technique is applied for encoding and decoding a digital message in a chaos-based communication. |
