Abstract

Coherent phonon manipulation is the mechanical analogy to photonic frequency combs while there is lack of a comprehensive evaluation system on the performance. In this paper, coherent phonon manipulation is demonstrated
using a single-mode circular electrostatic resonator. Its manipulation mechanism for controlling phononic frequency comb (PFC) parameters is verified experimentally and also theoretically based on waveform derivation of the differential equations. The spacing of PFC system is regulated solely by the pump frequency and a spacing resolution of 0.1 Hz is achieved at room temperature. The amplitude modulation law is investigated and a complete PFC evolution process with a pump threshold of 2 mVpp is achieved. The sweeping experiment of electrostatic resonators is explained from the perspective of phonons. Additionally, feasibility of manipulating phonons using the electrostatic resonators is verified through nonlinearity modulation and damping loss experiments. This new methodology of phonon manipulation can be extended to other resonant energy carriers, with great potentials for frequency detection and phonon-quantum computing.
