Injection characterization of packaged bi-directional diamond shaped ring lasers at 1550 nm
(The International Society for Optical Engineering (SPIE), 2006-05-12)
The Air Force Research Laboratory, Binoptics Corp., and Infotonics Technology Center worked collaboratively to package and characterize recently developed diode based ring lasers that operate at 1550 nm in a diamond shaped ...
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 ...
