JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]With COVID-19 now declared a pandemic by the World Health Organization, and states of emergency declared around the globe, the photonics market is starting to feel the impacts of the virus — global supply chains are beginning to slow, and prominent trade shows are beginning to see widespread cancellations and dropouts amid concern about the viral disease. The impact on the economy, according to Wayde Dazelle, a health economist and M.D. candidate at George Washington University, is varied but ultimately quite disruptive. An illustration showing the ultrastructural morphology...Read full articleRelated content from Photonics MediaARTICLESOptical Diagnostic Platform Detects Multiple Viruses in BloodUniversity of Rochester researchers are developing an optical chip on a disposable card that is capable of detecting exposure to multiple viruses, within a minute and from a single drop of blood. ...BioPhotonics Mar/Apr 2021 IssueVASCOVID Project Seeks to Improve Patient CareA newly launched project, VASCOVID, has been selected as one of 23 initiatives from the EU’s recent call for coronavirus research projects.

Acceptable BERs range from one error per billion to one per trillion bits transmitted. It is rare...Photonics HandbookSilicon Photonics: Light Is the Ultimate Medium for High-Speed Communications: Thanks to innovations with heterogeneous material integration and multiphotonic layer stacking, silicon photonics will drive optical solutions to high volumes and low costs.Silicon photonics is widely considered a key enabling technology for further development of optical interconnect solutions needed to address growing traffic on the internet.
