University of Auckland, NIST, and UMD Demonstrate Octave-Spanning Chip-Scale Microcomb in Nature

Researchers from the University of Auckland, NIST, UMD, and UC Santa Barbara have developed a chip-integrated optical frequency comb that addresses long-standing stability and control issues in microcomb metrology. They achieved this by inverting traditional frequency comb architectures, using two pump lasers an octave apart to generate a self-aligned, octave-spanning microcomb on a single chip. This innovation has significant implications for deployable optical atomic clocks, GPS-denied quantum navigation, and precision quantum sensing, with a provisional patent filed for commercialization.
