Abstract: An atomic clock stabilized or disciplined by tooth selected from a phononic comb of frequency teeth. A method of stabilizing an atomic clock having a reference oscillator, the method comprising selecting a particular tooth from a phononic comb of frequency teeth and applying a correction signal to said reference oscillator, the correction signal being based the selected tooth of said phononic comb. The disclosed technology is not limited to stabilizing reference oscillators associated with atomic clocks and thus may be utilized to stabilize reference oscillators whether or not they are interfaces with an atomic clock.
