摘要

Abstract

Compact terahertz (THz) functional devices are greatly sought after for high-speed wireless communication

biochemical sensing

and non-destructive inspection. However

controlled THz generation

along with transport and detection

has remained a challenge especially for chip-scale devices due to low-coupling efficiency and unavoidable absorption losses. Here

based on the topological protection of electromagnetic waves

we demonstrate nonlinear generation and topologically tuned confinement of THz waves in an engineered lithium niobate chip forming a wedge-shaped Su–Schrieffer–Heeger lattice. Experimentally measured band structures provide direct visualization of the THz localization in the momentum space

while robustness of the confined mode against chiral perturbations is also analyzed and compared for both topologically trivial and nontrivial regimes. Such topological control of THz waves may bring about new possibilities in the realization of THz integrated circuits

promising for advanced photonic applications.
