Synchronous Sisyphus effect in diode lasers subject to optical feedback
(American Physical Society, 1999-08)
Diode lasers exposed to moderate optical feedback, when biased near threshold, exhibit low-frequency intensity fluctuations in the RF spectrum that materialize as dropout events in the intensity time series. We recorded ...
Injection-locked semiconductor laser dynamics from large to small detunings
(The International Society for Optical Engineering (SPIE), 1999-08)
The equations for a semiconductor laser subject to injection are examined numerically and analytically
from large negative to moderate negative to positive values of the detuning. We concentrate on the
stability of the ...
Investigation of coupled diode laser dynamics using an electronic analog
(The International Society for Optical Engineering (SPIE), 1999-08)
We study the behavior of coupled semiconductor lasers using a reduced phase model that captures their
essential dynamics yet remains analytically tractable. We design a simple electronic circuit analog, a phaselocked
loop, ...
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, ...
Largely detuned injection-locked semiconductor lasers
(Elsevier Science B.V., 1999-01-01)
The equations for a semiconductor laser subject to injection are examined numerically and analytically for large values of the detuning parameter. Our analysis is motivated by recent experimental studies using either ...
Linewidth broadening across a dynamical instability
(Elsevier Science B.V., 1998-12-21)
We investigate experimentally and theoretically the variation of the emission linewidth of an optically-injected semiconductor laser across a resonant period-doubling bifurcation. Close to the dynamical instability, the ...
Self-organization of coupled nonlinear oscillators
(EDP Sciences, 1998-12-01)
The effects of impurities introduced into a lattice of strongly coupled oscillators are studied. Contrary to our expectations, a single impurity can control the chaotic behavior of a long array of chaotic oscillators and ...
Spatiotemporal organization of coupled nonlinear pendula through impurities
(American Physical Society, 1998-11)
We study the effect of impurities introduced into a lattice and their ability to control the dynamical behavior of arrays of coupled nonlinear chaotic oscillators. In particular we show that under certain conditions a ...
Synchronization of coupled semiconductor lasers
(The International Society for Optical Engineering (SPIE), 1998-07)
The dynamics of two mutually coupled semiconductor lasers is studied experimentally and numerically for weak coupling. The two lasers are pumped at different levels and have dissimilar free-running relaxation oscillation ...
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 ...
