Tunable Topological Directional Supercoupler and Applications in THz On‐Chip Communication

open access: yesLaser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.
A topological directional supercoupler is demonstrated, enabling dual‐channel 50 Gbps on‐chip terahertz communication with phototunable power splitting ratios. The achieved sub‐wavelength scale coupling area, sharp waveguide bends, and momentum‐conserved coupling process allow for ultra‐compact and efficient terahertz topological photonic integrated ...
