Google's Taara Hopes To Usher in a New Era of Internet Powered by Light
Alphabet's X division has developed a silicon photonic chip for its Taara project, which transmits internet via laser beams instead of fiber optic cables. The system delivers 20Gbps through "light bridges" that establish line-of-sight connections between transceiver units. The second-generation tech...
Alphabet's X division has developed a silicon photonic chip for its Taara project, which transmits internet via laser beams instead of fiber optic cables. The second-generation technology miniaturizes previous mechanical components-- including gimbals, mirrors, and lenses -- into solid-state circuitry the size of a fingernail.This chip enables a single laser transmitter to potentially pair with multiple receptors, significantly reducing costs from the current ~$30,000 per bridge setup. Taara has already demonstrated real-world viability by connecting Brazzaville and Kinshasa across the Congo River, providing the latter with five-fold cheaper internet access, and supplementing bandwidth at Coachella 2024.
