1. A phonic frequency comb system comprising:
a single frequency electrical input to provide an electrical signal comprising an amplitude and a single input frequency;
a single-mode mechanical resonator to receive the electrical signal, the single-mode mechanical resonator configured to produce at least one phononic frequency comb in response to a motion of the single-mode mechanical resonator caused by the electrical signal;
wherein the single-mode mechanical resonator comprises a piezoelectric structure having a resonance mode; and
wherein a value of the single input frequency equals twice a value of the resonance mode of the single-mode mechanical resonator.
