Mechanism for period-doubling bifurcation in a semiconductor laser subject to optical injection
(American Physical Society, 1996-06)
The single-mode rate equations for a semiconductor laser subject to optical injection are investigated analytically. We determine the first branch of periodic solutions for low values of the injection field. For larger ...
Period-doubling cascades and chaos in a semiconductor laser with optical injection
(American Physical Society, 1995-05)
We characterize the nonlinear dynamics of a semiconductor laser subject to optical injection. The key characteristics of measured optical spectra are reproduced in calculations based on a single-mode model that includes ...
Quasiperiodic synchronization for two delay-coupled semiconductor lasers
(American Physical Society, 1999-05)
The dynamical behavior of two mutually coupled semiconductor lasers is studied experimentally, numerically, and analytically for weak coupling. The lasers have dissimilar relaxation oscillation frequencies and intensities, ...
Localized synchronization in two coupled nonidentical semiconductor lasers
(American Physical Society, 1997-06-23)
The dynamics of two mutually coupled but nonidentical semiconductor lasers are studied experimentally, numerically, and analytically for weak coupling. The lasers have dissimilar relaxation oscillation frequencies and ...
All-optical double-sideband suppressed-carrier modulation of semiconductor lasers
(American Institute of Physics, 1998-06-15)
We demonstrate theoretically and verify experimentally that injection locking may be used to achieve double-sideband suppressed-carrier modulation of semiconductor lasers. Our theoretical investigation explains the suppression ...
Chaotic transitions and low-frequency fluctuations in semiconductor lasers with optical feedback
(Elsevier Science B.V., 2000-10)
This paper examines the dynamical origin of low-frequency fluctuations (LFFs) in semiconductor lasers subject to time-delayed optical feedback. In particular, we study chaotic transitions leading to the onset of LFFs by ...
Stability and bifurcations of periodically modulated, optically injected laser diodes
(American Physical Society, 2001-02)
Recent experiments using lasers subject to external injection
Averaged equations for injection locked semiconductor lasers
(Elsevier Science B.V., 2002-01-15)
An averaging method valid for strongly nonlinear oscillators is used for the first time to describe the pulsating intensity regimes of semiconductor lasers subject to injection. Slow-time equations are derived which are ...
Regular dynamics of low-frequency fluctuations in external cavity semiconductor lasers
(American Physical Society, 2001-05)
It is commonly believed that the dynamics responsible for low-frequency fluctuations (LFF’s) in external cavity semiconductor lasers is stochastic or chaotic. A common approach to address the origin of LFF’s is to investigate ...
Using neural networks for controlling chaos
(The International Society for Optical Engineering (SPIE), 1994-03)
A feed-forward backpropagating neural network is trained to achieve and maintain control of the unstable periodic orbits embedded in a chaotic attractor. The controlling algorithms used for training the network are based ...
