Abstract
Topological photonic crystals have emerged as an important branch of physics for their excellent ability to manipulate light. Furthermore, a large-area photonic crystal can provide an additional degree of freedom by inserting a photonic crystal structure without a band gap between topologically distinct photonic crystals. In this article, we propose a hybrid topological heterostructure with the potential to be applied in modern communication. The time-reversal symmetry is broken by applying an external magnetic field while the spatial-inversion symmetry is broken by rotating the dielectric components. Our system exhibits the characteristics of large-area one-way transmission that evenly distributes over the middle domain. The unidirectional excitation properties and inherent robustness are verified in a Z-shaped channel. The proposed heterostructure provides broad application prospects in photonic integrated networks and on-chip integrated communication systems.
