To achieve ultrafast neuromorphic signal processing, the realization of photonic equivalents to neuronal functions has been challenged. In article number 1900771, Namkyoo Park and co‐workers present a neuromorphic photonic system ruled by parity‐time symmetry as a building block for light‐based neural signal processing. Inspired by neuronal ion channels, saturable photonic channels using coupled resonators are developed to achieve multifaceted neuromorphic functionalities such as quenching and firing.
