Multi-order phononic frequency comb generation within a MoS2 electromechanical resonator

Résumé

In this work, we measure and tune simultaneously the vibration of a 1-nm thick MoS 2 suspended monolayer with standard electrical excitation and optical techniques. At ambient temperature, we first investigate the strong parametric coupling between two different mechanical modes (x 1 and x 2). We demonstrate a high and quasi-linear tunability of the mode frequencies with the parametric pump voltage. Then, we couple the highly tunable main vibration (x 1) to a parametric pump frequency (x p) to obtain a high number of sidebands at frequencies x 1 6 m x p , driving the mechanical mode with a large external electrical force. This oscillating force, applied via the gate voltage, acts as a stress onto the MoS 2 sheet. The obtained frequency comb has a large spectral band and contains up to 100 harmonics, with potential applications in quantum information processing and heat or sound transport.
