High-quality Kerr resonators are a key platform for studying nonlinear optical phenomena, where bifurcations such as optical bistability and spontaneous symmetry breaking are both of theoretical and practical significance. In this work, we present an analytical framework, which allows finding the stationary states and their bifurcations for the propagating fields in Kerr ring and Fabry-Perot resonators. Using tools from nonlinear algebra, namely, polynomial resultants and Groebner bases, we derive compact polynomial expressions describing the system full solution in both intensity and amplitude representations. The bifurcations are derived from these expressions, and are additionally characterized as exceptional points of an auxiliary linear non-Hermitian system. This work unifies key phenomena in Kerr resonators under the broader framework of nonlinear algebra and offers better control of nonlinear optical systems and the design of photonic devices, enabled by full analytic control.
