"normal-dispersion Kerr hybrid microcomb capable of reaching difficult to access spectral bands... rotated racetrack-shaped resonator suppresses interference... requires significantly less power... provides wider line spacing for high-speed telecommunications/ spectroscopic sensors... combs coexist with high-speed electro-optical controls on same mm-scale circuit... miniaturized atomic clocks, gas sensors, and ultra-fast data communication systems"
