Dual-Band Topological Valley Cavity in Mid-Infrared Range

Dual-Band Topological Valley Cavity in Mid-Infrared Range

Topological edge states, emerging at boundaries between regions with distinct topological properties, enable unidirectional transmission with robustness against defects and disorder. However, achieving dual-band operation with high performance remains challenging. Here, we integrate dual-band topolo...
