Abstract
Finite-element simulations of optical cavities are presented, showing frequency splittings in the resonance spectrum. These results support the theoretical framework and experimental observations presented in van Exter et al. (2022, Phys. Rev. A 106, 013501), Koks et al. (2022, Phys. Rev. A 105, 063502) and Post et al. (2025, Phys. Rev. A 112, 033537). The simulated (fine) structure in the spectrum can be characterized by mirror-shape and nonparaxial effects including spin-orbit coupling. These simulations also provide model-independent predictions of modal losses for optical cavities.
