For decades, satellites have been beaming data from Earth to space and back via radio waves. But with the growing number of spacecraft in orbit and the increasing quantities of data beaming back to Earth, radio spectrum is hitting its physical limits. For about a decade, companies and research institutions have been working on higher-bandwidth, optical technologies that would remove current data transmission bottlenecks . Perhaps the most ambitious among those companies is Singapore-based deep-tech...
