Experimental investigation of solitary structures in a nonlinear optical feedback system

Abstract We investigate phenomena of spontaneous pattern formation in a nonlinear optical feedback experiment using an optically addressable liquid crystal light valve in the polarization mode as a nonlinear optical element. Depending on the initial detuning, transitions between different types of patterns are observed. In a certain range of this control parameter the evolution of bright solitary spots is examined and the typical scaling behavior of noncritical slowing down in the switching characteristics is found.
