Topological Photonic Crystals: Physics, Designs, and Applications

Guo-Jing Tang et al.

Summary: Recent research in topological photonics has made significant progress in proposing and realizing novel topological phenomena, designing and fabricating high-performance photonic devices. Photonic crystals, as a powerful platform for controlling the flow of light, have been widely used to reveal different topological phases of light and demonstrate topological photonic functionalities. Furthermore, topological photonic crystals have found applications in both passive and active photonics.

Critical couplings in topological-insulator waveguide-resonator systems observed in elastic waves

Si-Yuan Yu et al.

Summary: Waveguides and resonators are core components in the integration of electronics, photonics, and phononics, with the potential for signal filtering, switching, multiplexing, and sensing. Introducing topological insulators into classical waveguide-ring-resonator configurations can eliminate upstream reflections and retain useful transmission spectral characteristics, offering advantages in novel signal processing, sensing, lasering, energy harvesting, and wave-matter interactions. This study contributes to the confidence in utilizing topological protection for practical device performance, suggesting further research opportunities in advancing phononics/photonics technologies.

Investigation of corner states in second-order photonic topological insulator

Shi-lei Shen et al.

Summary: This study investigates the influence of BNN interaction on photonic higher-order corner states, finding two kinds of corner states different from traditional zero-energy state, and designing a novel structure to distinguish contributions from NNN hopping and PEC boundaries. The total contribution on corner states when NNN couplings and PEC boundaries coexist is also examined, revealing some interesting features that may expand understanding of high-order corner modes in a more general framework.
