PITCHFORK BIFURCATION, CRISIS, AND FLIP-FLOP OPERATION IN A 2-ELEMENT OPTICAL BISTABLE DEVICE

Abstract

Flip-flop operation and the pitchfork bifurcation in a coupled element optical bistable device are studied. In the long delay limit, the dynamics is described by a two-dimensional mapping. Within a pitchfork bifurcation structure, a flip-flop operation is found. However, this flip-flop operation cannot be realized when a boundary crisis appears due to the increase of the input intensity.
