Abstract

Dynamical behavior in a chaotic system drastically changes, depending sensitively on system parameters or initial conditions. Therefore, a variety of temporal variations can be obtained with only small perturbation on the dynamical system. Lima and Pettini suggested that a weak periodic modulation of one of the system parameters may transfer the chaotic motion into the periodic one.¹ Recently, Meucci et al. employed this technique to stabilize an unstable pulsation of a chaotic laser whose cavity loss was periodically modulated by an electro-optic device.²
