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) ...
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 ...
Fractal dimensions in tunneling processes and effects of environmental fluctuations
(World Scientific Publishing, 1998-03)
We study electron tunneling between two infinte potential square wells connected via an opaque barrier and find that time evolution of the probability of the presence of a Gaussian wave packet, localized initially in one ...
Instabilities and chaos in optically injected semiconductor lasers
(American Institute of Physics, 1995-11-06)
We have experimentally obtained and theoretically analyzed a systematic map of the various instabilities induced in a semiconductor laser subject to strong optical injection as the amount of optical injection power and ...
Period-doubling route to chaos in a semiconductor laser subject to optical injection
(American Institute of Physics, 1994-06-27)
Experimental measurements and a single-mode analysis of a quantum-well laser diode subject to strong optical injection are combined to demonstrate that the diode follows a period-doubling route to chaos. All laser parameters ...
Subharmonic transition in an optically injected semiconductor laser: theory and experiments
(Institute of Physics, 1997-08)
The equations for a semiconductor laser subject to detuned optical injection are analysed using asymptotic methods. We derive a third-order equation for the phase of the laser field which is then investigated for small ...
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 ...
