Paper Abstract

The mathematical models of dispersive optical bistability in unidirectional ring cavity yield the transmitted intensity It as a function of the input intensity Iin with additional parameters (mirror reflectivity R and phase shift β). There are two feedback elements in this description: the energy (and, hence, also causal) feedback quantified by R and the purely causal feedback given by dependence of the phase shift on the transmitted power, β=β02It. The apparatus of causal diagrams method is used to represent and analyze phenomena in the ring cavity. The region of physically unstable states is marked by the condition tloop>1, where tloop is the transmission function of the feedback loop ItβIinIt present in the diagram. Besides the critical points defined by tloop=1 (which are linked to the existence of bistability), there are two conditions marked by tloop=0 in which the cavity state is insensitive to the values of R.
