PASSION Project Attempts Using VCSELs for Ultra-High-Speed, Long-Distance Data Transmission

Vertical cavity surface emitting lasers or VCSELs are laser diodes that are inexpensive to make and more energy efficient than standard lasers. Now, a group of EU-funded researchers intends to use VCSELs to deliver ultra-high-speed broadband across long distances. This effort has the potential to end the data bottlenecks experienced …
