Article Synopsis
- Undesirable light scattering, particularly Rayleigh backscattering, reduces photon efficiency in nanophotonics, especially in wave-guiding systems due to material and geometric defects at tiny scales.
- The research introduces a method to dynamically suppress Rayleigh backscattering using chiral dispersion linked to broken time-reversal symmetry, showcasing its effectiveness in integrated photonic systems.
- Experiments conducted with lithium niobate resonators demonstrate nearly complete suppression of this backscattering, supporting the theory that it can be understood as a form of topological protection in a synthetic framework.
On-chip generation of optical frequency combs using nonlinear ring resonators has enabled numerous applications of combs that were otherwise limited to mode-locked lasers. Nevertheless, on-chip frequency combs have relied predominantly on single-ring resonators. In this study, we experimentally demonstrate the generation of a novel class of frequency combs, the topological frequency combs, in a two-dimensional lattice of hundreds of ring resonators that hosts fabrication-robust topological edge states with linear dispersion.

Imaging studies revealed an endoluminal carinal mass and a tumoral mass arising from the posterior wall of the trachea was observed bronchoscopically.
