Simulating frequency splittings and loss in Fabry-P\'erot cavities

Joep K. van den Brink, Jonah Post, Martin P. van Exter

Finite-element simulations show that frequency splittings in Fabry-Perot cavity spectra arise from mirror-shape deviations and nonparaxial effects including spin-orbit coupling, while also yielding model-independent modal loss predictions.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

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.

C2weakest assumption

That the finite-element discretization and boundary conditions faithfully reproduce the physical cavity behavior without introducing numerical artifacts that could be mistaken for the reported splittings or losses.

C3one line summary

Finite-element simulations confirm frequency splittings in Fabry-Pérot cavity resonances from mirror-shape and nonparaxial effects, and provide predictions for modal losses.
