Amplitude modulation in a pair of time-delay coupled external-cavity semiconductor lasers
(Elsevier Science B.V., 2003-11-03)
The phenomenon of amplitude death in coupled nonlinear oscillators has been a topic of recent interest. We demonstrate
that a similar phenomenon can occur in a pair of time-delay coupled, external-cavity semiconductor ...
Complicated basins in external-cavity semiconductor lasers
(Elsevier Science B.V., 2003-07-21)
We demonstrate that complicated basins of attraction can occur in time-delay coupled, external-cavity semiconductor lasers.
In particular, we find that there can be multiple coexisting attractors associated with low-frequency ...
Bistability of pulsating intensities for double-locked laser diodes
(American Physical Society, 2002-05)
Rate equations for semiconductor lasers subjected to simultaneous near-resonant optical injection and microwave current modulation are examined by combined analytical-numerical bifurcation techniques. Simple qualitative ...
Period three limit-cycles in injected semiconductor lasers
(Institute of Physics Publishing, 2002-02)
Experiments showing period three intensity oscillations are reported for a semiconductor laser subject to external injection. These oscillations appear close to a period doubling bifurcation of the fundamental laser ...
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 ...
Low-frequency fluctuations in external cavity semiconductor lasers: understanding based on a simple dynamical model
(Institute of Physics, 2001-08)
We investigate the dynamical origin of low-frequency fluctuations (LFFs) in external cavity semiconductor lasers by utilizing a simplified, three-dimensional model derived from the infinite-dimensional Lang-Kobayashi (LK) ...
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 ...
Stability and bifurcations of periodically modulated, optically injected laser diodes
(American Physical Society, 2001-02)
Recent experiments using lasers subject to external injection
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 ...
Bifurcation to mixed external cavity mode solutions for semiconductor lasers subject to optical feedback
(Elsevier Science B.V., 2000-09-15)
The Lang and Kobayashi equations modeling a semiconductor laser subject to optical feedback admit time-periodic solutions which are combinations of two distinct external cavity modes. We construct these solutions analytically ...
