Encoding and decoding messages with chaotic lasers
(American Physical Society, 1997-12)
We investigate the structure of the strange attractor of a chaotic loss-modulated solid-state laser utilizing return maps based on a combination of intensity maxima and interspike intervals, as opposed to those utilizing ...
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 ...
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 ...
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) ...
