Abstract

Abstract : In article number 2000569 by Haitan Xu, Fuchuan Lei, Dong Ruan, Gui‐Lu Long, and co‐workers, exceptional surfaces are experimentally realized in the higher‐dimensional synthetic space. The unidirectional coupling between two degenerate modes is achieved, benefitting from an ingenious design within a single whispering‐gallery‐mode microresonator. The sensor operating at an exceptional surface combines enhanced sensitivity with flexible experimental conditions.
