Chip based microcombs boost gps precision

Berlin, Germany (SPX) Feb 24, 2025 Optical atomic clocks hold the promise of enhancing timekeeping and positioning in everyday devices by a factor of one thousand. Yet their large size and complex design have kept them confined to advanced laboratories. Researchers at Purdue University, USA, and Chalmers University of Technology, Sweden, have now devised a method using on-chip microcombs to dramatically reduce the size of these p
