Optoelectronic chaos

摘要

Optoelectronic circuits with delayed feedback provide a convenient bench-top platform to study a wide range of nonlinear dynamic systems, from ultrastable clocks to complex chaotic devices.rnEvery time we turn on a computer we are reminded that nothing happens instantaneously. All physical systems exhibit a finite time delay between the moment we provide a stimulus and the moment the system returns a response. In many situations, the response also depends nonlinearly on the input, such that the evolution of the system in the present depends very sensitively on its state in the past.
