Abstract
Spontaneous symmetry breaking (SSB) is said to have occurred when two or more properties of a system suddenly change from having equality between them (symmetric) to having an inequality (asymmetric) following an in-finitely small change to some system parameter. Recently there has been rapid growth of research on SSB in Kerr resonators, for examples, between two counterpropagating light fields [1], and two orthogonally polarized modes [2]. In this work [3], we describe novel mechanisms for SSB, which cause four field symmetry breakings [4] in two different photonic molecule structures (two coupled ring resonators) with different field coupling mechanisms.
