About this Research Topic
Topological photonics provides a new platform to study the interactions between light and matter based on a topological degree of freedom, and has been one of the hottest research frontiers in optics and photonics in recent years. Some new physical phenomena, such as unidirectional surface states, bulk–disclination correspondence, Non-Hermitian skin effect, etc. have already been revealed. Owing to the unique topological protection, various novel photonic devices, including topological laser, topological quantum light source, have been developed successfully. Topological states have been used to realize various functions of photonic devices. Further research into these systems is expected to reveal new physics, offer new approach to better understanding light-matter interaction mechanism, and present important applications in photonic circuits, optical communication, and quantum information processing, which are the transformative technologies changing our lives.
Even though the study of photonic topological insulators in Hermitian systems has achieved great success, new discoveries and novel physics therein, such as synthetic dimension, non-Hermitian topology, high-order topology, and quantum effects, continue to fuel the development of topological photonics. This Research Topic aims to exchange the latest research progress, and promote the development of topological photonics in these new directions.
The scope of the Research Topic will include but not limited to
1. Design, fabrication, and measurement of photonic topological insulators
2. Synthetic dimensions
3. Non-Hermitian and PT-symmetric optics
4. High-order topological states
5. Topological properties of photonic crystals and metamaterials
6. Quantum topological photonics
7. Applications of topological photonic system
8. Topological physics in integrated circuits.
9. Other related areas, such as topological microwaves, topological acoustics, etc.
