Abstract
In this work, we present a photonic scheme for controlling and tuning the strength of exceptional points (EPs) and their transition to diabolic points (DPs). The proposed scheme utilizes exceptional surface geometry in conjunction with a standard Mach–Zehnder interferometer to create a tunable mirror. The functionality of this structure is validated through full-wave simulations, demonstrating its potential for the dynamic manipulation of EPs and DPs. Importantly, our scheme can be implemented using standard on-chip photonics technology.
