• Abstract

  This proposal explores the non-linear coupling of light in chains of coupled microring resonators, photonic molecules, to engineer spontaneous symmetry breaking (SSB) phenomena with both classical and quantum functionalities. In Kerr microresonators, SSB arises from the interplay between self and cross-phase modulation, giving rise to rich nonlinear dynamics and highly tunable optical res…
