Amplitude modulation in a pair of time-delay coupled external-cavity semiconductor lasers
Prasad, Awadhesh; Lai, Ying-Cheng; Gavrielides, Athanasios; Kovanis, Vassilios (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 ... -
Chaotic transitions and low-frequency fluctuations in semiconductor lasers with optical feedback
Davidchack, Ruslan; Lai, Ying-Cheng; Gavrielides, Athanasios; Kovanis, Vassilios (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 ... -
Complicated basins in external-cavity semiconductor lasers
Prasad, Awadhesh; Lai, Ying-Cheng; Gavrielides, Athanasios; Kovanis, Vassilios (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 ... -
Dynamical origin of low frequency fluctuations in external cavity semiconductor lasers
Davidchack, Ruslan; Lai, Ying-Cheng; Gavrielides, Athanasios; Kovanis, Vassilios (Elsevier Science B.V., 2000-03-27)Low-frequency fluctuations (LLFs) in semiconductor lasers subject to time-delayed optical feedback from external reflectors have been experimentally observed and theoretically studied for the past two decades. Yet recently ... -
Low-frequency fluctuations in external cavity semiconductor lasers: understanding based on a simple dynamical model
Prasad, Awadhesh; Lai, Ying-Cheng; Gavrielides, Athanasios; Kovanis, Vassilios (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
Davidchack, Ruslan; Lai, Ying-Cheng; Gavrielides, Athanasios; Kovanis, Vassilios (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 ...
