Insulator-free topological photonic multi-lane highways
Merged summary
TL;DR - A topological waveguide architecture enables robust, multi-lane, unidirectional light transport without insulating layers. Its closely stacked design achieves 100% spatial efficiency, potentially enabling denser photonic routing.
- Uses four inequivalent photonic valley half-semimetals in a parallel, cyclic configuration.
- Eliminates the insulating separation typically used between topological waveguides.
- Supports robust one-way light propagation across multiple lanes.
- Closely stacked lanes retain 100% spatial efficiency.
