What is it about?
Photonic corner states are highly trapped zero-dimensional topological electromagnetic modes, and they usually hybridize with each other. This work explores the origin caused the hybridization of photonic corner states and the potential device applications.

Why is it important?
Exploring the origin of photonic corner state degeneracy can deepen our understanding of complex topological states, and also bring many important applications such as corner mode lasing with tunable frequency, emission position and beam numbers etc. Furthermore, the role of local symmetry in protecting higher-order topological states is revealed.
