Microcomb chips help pave the way for thousand times more accurate GPS systems
Optical atomic clocks can increase the precision of time and geographic position a thousandfold in our mobile phones, computers, and GPS systems. However, they are currently too large and complex to be widely used in society. Now, a research team has developed a technology that, with the help of on-chip microcombs, could make ultra-precise optical atomic clock systems significantly smaller and more accessible -- with significant benefits for navigation, autonomous vehicles, and geo-data monitoring.
