In this article, we propose and numerically demonstrate a novel dual-phase modulated time-delay signature (TDS) concealed communication system. The proposed system addresses the fatal disadvantage of conventional electro-optic chaotic systems in that TDS

Numerical Analysis of Nonlinear Dynamics Based on Spin-VCSELs with Optical Feedback
In this paper, the nonlinear dynamics of a novel model based on optically pumped spin-polarized vertical-cavity surface-emitting lasers (spin-VCSELs) with optical feedback is investigated numerically.

Experimental investigations of Synchronization in two optically coupled chaotic systems utilizing optical feedback and optical injection [PDF]
An experimentally observations of chaos synchronization have been investigated between two optically coupled laser diodes. Two schemes of optical injection, bidirectional and unidirectional optical injections have been used.

AC/DC: The FERMI FEL Split and Delay Optical Device for Ultrafast X-ray Science
Free-electron lasers (FELs) are the most advanced class of light-sources, by virtue of their unique capability to lase high-brightness pulses characterized by wavelengths spanning the extreme-ultraviolet, the soft and hard X-ray spectral domains, as well

Optical Feedback Radiation Forces: Intracavity Optical Trapping with Feedback-locked Diode Lasers [PDF]
We demonstrate a novel mechanism for optical tweezing, where a trapped particle dynamically alters an external cavity quality factor, reduceing the average intensity and photodamage, even employing low-numerical aperture lenses and wide fields-of-view.

All-optical versus electro-optical quantum-limited feedback [PDF]
21 pages. This is an old (1994) paper, but one which I thought was worth posting because in addition to what is described in abstract it has: (1) the first formulation (to my knowledge) of quantum trajectories for an arbitrary (i.e. squeezed, thermal etc.) broadband bath; (2) the prediction of a periodic modification to the detuning and damping of an ...
