Experimental synchronization of chaos in diode lasers with polarization-rotated feedback and injection.

Square-wave self-modulation in diode lasers with polarization-rotated optical feedback.

The square-wave response of edge-emitting diode lasers subject to a delayed polarization-rotated optical feedback is studied in detail. Specifically, the polarization state of the feedback is rotated such that the natural laser mode is coupled into the orthogonal, unsupported mode. Square-wave self-modulated polarization intensities oscillating in antiphase are observed experimentally. We find ...

Chaotic dynamics in semiconductor lasers subjected to polarization-rotated optical feedback

Synchronization of feedback-induced chaos in semiconductor lasers by optical injection

In this paper, synchronization of chaotic oscillations in semiconductor lasers by optical injection in a transmitter-receiver configuration is studied numerically. A chaotic signal is generated from a semiconductor laser with optical feedback in the transmitter and is injected into the receiver laser without optical feedback. We examined the conditions of chaotic synchronization in the system. ...

Chaos Synchronization and Chaotic Signal Masking in Semiconductor Lasers With Optical Feedback

Theoretical and experimental investigations of chaos synchronization and its application to chaotic data transmissions in semiconductor lasers with optical feedback are presented. Two schemes of chaos synchronization—complete and generalized synchronization—are discussed in the delay differential systems. The conditions for chaos synchronization in the systems and the robustness for the paramet...

Tunable Photonic Mircrowave Oscillator Self-locked by Polarization-rotated Optical Feedback (preprint)

Combining optical injection and polarization-rotated optical feedback in a semiconductor laser can induce selfreferenced periodic output that is widely tunable by simply varying the dc-bias points of the master and slave lasers. We observed feedback-induced reduction of the pulsation peak linewidth by more than two orders of magnitude relative to the injection-only case. The nonlinear dynamics ...
