Sisyphus effect in semiconductor lasers with optical feedback
TLDR
In this article, the authors identify the various physical mechanisms in low frequency fluctuations, which occur when a semiconductor laser is subject to moderate optical feedback while operating close to its solitary laser threshold.Abstract:
We identify the various physical mechanisms in low frequency fluctuations, which occur when a semiconductor laser is subject to moderate optical feedback while operating close to its solitary laser threshold. In attempting to reach the maximum gain mode, which often is stable, the system forms short mode-locked pulses. In between pulses mode-slipping can occur, generally in the direction of maximum gain. Inevitably, the trajectory passes too close to one of the many saddle points, which will take the system back to the solitary laser state. >read more

Ultrahigh-speed random number generation based on a chaotic semiconductor laser.
TL;DR: The fluctuating intensity of a chaotic semiconductor laser is used for generating random sequences at rates up to 12.5 Gbits/s and the overall rate of generation is much faster than any previously reported random number generator based on a physical mechanism.

Dynamics of semiconductor lasers subject to delayed optical feedback: the short cavity regime.
TL;DR: In this paper, the authors give experimental and numerical evidence for a new dynamical regime in the operation of semiconductor lasers subject to delayed optical feedback occurring for short delay times, and demonstrate that these regular pulse packages correspond to trajectories moving on global orbits comprising several destabilized fixed points within the complicated phase space structure of this delay system.

Sensitivity of quantum-dot semiconductor lasers to optical feedback.
TL;DR: In this article, the sensitivity of quantum-dot semiconductor lasers to optical feedback was analyzed with a Lang-Kobayashi approach applied to a standard quantum dot laser model, where the carriers are injected into a quantum well and are captured by, or escape from, the quantum dots through either carrier-carrier or phononcarrier interaction.

Chaos in semiconductor lasers with optical feedback: theory and experiment
TL;DR: In this paper, the authors present a detailed theoretical and experimental investigation of the nonlinear dynamics of a semiconductor laser with optical feedback, showing that the coherence collapsed state is a chaotic attractor and that chaos is reached for increasing feedback level through a quasi-periodic route interrupted by frequency locking.

N. Schunk,Klaus Petermann +1 more
TL;DR: In this article, the effect of external feedback on a single-mode semiconductor laser is estimated by a numerical solution of the nonlinear rate equations, and it is found that the lasing mode with the minimum linewidth is most stable rather than the mode with minimum threshold gain.
