dc.description.abstractAn experimental setup of three coupled PT -symmetric waveguides showing the characteristics of a third-order exceptional point (EP3) has been investigated by Heiss and Wunner in an idealized model of three δ-function waveguides [W. D. Heiss and G. Wunner, J. Phys. A 49, 495303 (2016)]. Here we extend these investigations to realistic, extended waveguide systems. We place major focus on the strong parameter sensitivity rendering the discovery of an EP3 a challenging task. We also investigate the vicinity of the EP3 for further branch points of either cubic- or square-root-type behavior.en_ZA
