Broadband chaos generated by an optoelectronic oscillator.
Abstract
We study an optoelectronic time-delay oscillator that displays high-speed chaotic
behavior with a flat, broad power spectrum. The chaotic state coexists with a linearly
stable fixed point, which, when subjected to a finite-amplitude perturbation, loses
stability initially via a periodic train of ultrafast pulses. We derive approximate
mappings that do an excellent job of capturing the observed instability. The oscillator
provides a simple device for fundamental studies of time-delay dynamical systems and
can be used as a building block for ultrawide-band sensor networks.

Daniel J. Gauthier
Research Professor of Physics
Prof. Gauthier is interested in a broad range of topics in the fields of nonlinear
and quantum optics, and nonlinear dynamical systems.
In the area of optical physics, his group is studying the fundamental characteristics
of highly nonlinear light-matter interactions at both the classical and quantum levels
and is using this understanding to develop practical devices.
At the quantum level, his group has three major efforts in the area of quantum communication
and networking. I
