摘要

A novel topological photonic logic operator is proposed in this paper. By utilizing the magnetic photonic crystal, we realize a two-mode topological chiral edge state and separate them freely by adjusting the sources. Basing on phase cellulation, we realize photonic exclusive OR operation in a high accuracy due to topological protection. Our work paves a new way for future optical device and photo-communications.
