A new device for analyzing partial coherence in integrated photonic networks

Generation of multimode partially coherent light by PCLA. Credit: Light: Science & Applications (2024). DOI: 10.1038/s41377-024-01622-y Anyone familiar with optical labs is familiar with the limits of optical coherence. Laser beams are highly coherent and produce well-defined interference patterns that are used in precision applications such as atomic manipulation and precision sensing. In contrast, light from a light source such…
