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…

Road networks stretching into the forests of the Congo Basin: satellites and AI help monitor
Road development in the Congo Basin forests over the past five years. Credit: Remote Sensing of Environment (2024). DOI: 10.1016/j.rse.2024.114380 The Congo Basin rainforests are the second largest tropical forests in the world, store large amounts of carbon and host high levels of biodiversity. Historically these forests have remained largely intact, but more recently road development has posed a significant…
