JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]NEW YORK, Feb. 11, 2021 — A team at Columbia University has introduced a way to program a layered crystal in such a way that it is able to open doors to imaging capabilities beyond common limits, on demand. The technique exerts control over nanolight — light that is able to access the nanoscale — providing insight into the field of optical quantum information processing. Light can only be focused down to a certain level, referred to as the Abbe limit. At this point, to a traditional optical microscope, objects that are closer than this limit would appear as one. Under certain conditions, however,...Read full articleRelated content from Photonics MediaArticlesShortwave System Captures Photoluminescence Lifetime in One ShotAn imaging system developed by researchers from the Institut national de la recherche scientifique (INRS) captures the photoluminescence lifetimes of rare-earth doped nanoparticles in the micro- to...Photonics Spectra April 2024 IssueImaging Technique Enables 20-nm Resolution on Standard MicroscopesA new expansion microscopy (ExM) technique from MIT makes it possible to use a conventional light microscope to generate high-resolution images at the nanoscale, by expanding specimens 20-fold before...BioPhotonics.com October 2024 IssueDeep Learning-Based Method Guards Against Chip TamperingThe $75 billion counterfeit chip market jeopardizes the safety and security of multiple sectors that depend on semiconductor technologies, including aviation, communication, quantum computing,...Photonics Spectra December 2024 IssueAI-aided Implant Captures Deep Brain ImagesA neural implant developed at the University of California San Diego could help advance the path to minimally invasive brain-computer interface (BCI) technology.
