Scaling Behavior Of Optical Bistability In Nonlinear Medium
Yao‐Huang Kao, Ching-Sheu Wang
Optical bistability in nonlinear media is potentially useful because of its fast transition speed for all-optical logic operation [1-3]. The dynamics of these mirrorless systems have been described by a anharmonic Duffing oscillator [1-4]. After normalization the equation of motion is described by x + k x + x - f(x) = F sinwt, where k is the damping factor, F is the driving amplitude, w is the driving frequency and f(x) is a nonlinear function of x. Such a model predicts the existence of bistability under appropriate conditions [3]. It would be particularly important for this system to be tuned to some situation in order to efficiently generate these nonlinear phenomena. In this summary we would provide a global picture of possible dynamic behaviours in Eq.(1), which can be used as a guide line in real experiment.
