JUSTINE MURPHY, SENIOR EDITOR, [email protected] The Conference on Lasers and Electro-Optics (CLEO), under The Optical Society (OSA) and to be held May 13-18 in San Jose, is a technology playground. It showcases optoelectronics technologies and lasers, in addition to research findings and industry applications. Attendees can examine new scientific ideas, engineering concepts, and emerging applications in fields such as biophotonics, optical communications, and light sources. This year, CLEO will include a celebration of the International Day of Light — May 16 — with special plenary sessions. Those who are not attending...Read full articleRelated content from Photonics MediaArticlesAction-Packed Trailer Kicks Off International Day of Light 2022Three photonics professional societies partnered to kick off the International Day of Light, May 16, with a stylized trailer for a movie titled “Day of Light.” In the trailer, a diverse...Photonics.com 5/16/2022CLEO Welcomes Optics and Photonics Industry to Silicon ValleyFeaturing a program of more than 2000 technical sessions across 29 topic categories, plus plenary sessions, special symposia, and short courses, the Conference on Lasers and Electro-Optics (CLEO)...Photonics.com 5/1/2023Ocean Insight Names President; Bluglass, TeraXion Add to Executive Teams: People in the News: 09/13/2023ZEISS CFO Christian Müller will step down from the executive board at the end of this month.
