Microcomb (IMAGE)
Caption
Like the teeth of a comb, a microcomb consists of a spectrum of evenly distributed light frequencies. Optical atomic clocks can be built by locking a microcomb tooth to a ultranarrow-linewidth laser, which in turn locks to an atomic transition with extremely high frequency stability. That way, frequency combs act like a bridge between the atomic transition at an optical frequency and the clock signal at a radio frequency that is electronically detectable for counting the oscillations – enabling extraordinary precision. The researchers’ photonic chip contains 40 microcombs generators and is only five millimeters wide.
