Chiral exceptional point enhanced active tuning and nonreciprocity in micro-resonators
Hwaseob Lee, Lorry Chang, Ali Kecebas +6
Exceptional points (EPs) have been extensively explored in mechanical, acoustic, plasmonic, and photonic systems. However, little is known about the role of EPs in tailoring the dy…
