Summary
This study presents a groundbreaking achievement in the generation of mechanical soliton frequency combs within an electrostatic NEMS resonator. Our approach relies on a single NEMS resonator offering remarkable simplicity and efficiency. Our method relies on an intricate interaction among multiple vibration modes of a bracket-nanocantilever under excitation by a continuous-wave (CW) laser source and an electric wave source. Enabled by the strong nonlinearity of the electrostatic field, they orchestrate the formation of mechanical wave packets represented by zero-centered state I and state II solitons, each featuring hundreds of equally spaced peaks at the electrical excitation frequency. In time domain, the FCs take the form of a periodic train of narrow pulses, a highly coveted phenomenon within the realm of nonlinear wave-matter interactions. This breakthrough has a transformative potential across various fields, including quantum computing and spectroscopy.
