Synthetic gauge fields directed into ultra-dense photonic waveguide arrays enable dispersionless coupling across broad wavelength bands
https://www.eurekalert.org/news-releases/1151262 Summary: By modulating inter-waveguide phase relationships, the integrated photonic architecture suppresses chromatic dispersion and crosstalk between closely spaced optical channels. This dispersionless coupling control enables compact optical phased arrays with ultra-wide fields of view, providing high-performance optical routing components for LiDAR sensors and silicon photonic interconnects.
