Lang and Kobayashi phase equation
(American Physical Society, 1996-06)
Lang and Kobayashi equations for a semiconductor laser subject to optical feedback are investigated by using asymptotic methods. Our analysis is based on the values of two key parameters, namely, the small ratio of the ...
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 ...
Lang and Kobayashi phase equation and its validity for low pump
(The International Society for Optical Engineering (SPIE), 1996-05)
An asymptotic theory of Lang and Kobayashi (LK) equations describing a semiconductor laser subject to optical feedback is investigated in detail. We obtain a simple third order, nonlinear, delay-differential equation for ...
Cavity enhancement of resonant frequencies in semiconductor lasers subject to optical injection
(American Physical Society, 1995-12)
The injection of an optical signal into a semiconductor laser biased near or above the lasing threshold modifies the coupling between the free carriers and the intracavity field. The detuning between the frequency of the ...
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 ...
Synchronization and control in a unidirectionally coupled array of chaotic diode resonators
(American Physical Society, 1995-06)
We experimentally investigate the synchronization of a one dimensional array of unidirectionally coupled chaotic diode resonators. Though care is taken to match diode elements as closely as possible, slight differences in ...
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 ...
Controlling chaos may induce new attractors in an optical device
(Elsevier Science, B.V., 1995-04-01)
The logistic map has been used to describe period doubling bifurcations for periodically modulated lasers. It also represents an asymptotic approximation of Ikeda's map for a passive ring cavity. Because various control ...
Synchronization of chaotic resonators based on control theory
(American Physical Society, 1995-04)
We have investigated experimentally and computationally a synchronization scheme, based on control theory, for the case of two nearly identical chaotic diode resonators. From the experimentally captured time series we ...
History-dependent control of unstable periodic orbits
(American Physical Society, 1994-09)
We present a method of stabilizing unstable periodic orbits in systems whose natural time scales are on the order of or faster than the time it would take for the experimental implementation of the Ott-Grebogi-Yorke (OGY) ...
