Résumé

We report on self-sustained oscillations studied on geometrically different mechanical devices embedded in a microwave optomechanical setup. A strong blue-detuned pump signal (at a frequency shifted up from the cavity by the mechanical frequency) triggers the parametric instability. Two different NEMS (Nano-Electro-Mechanical Systems) dynamics are compared: the ones of a doubly-clamped beam [1] and of a drumhead[2]. Measurements have been carried out from 1 K down to 10 mK for different applied microwave powers and detunings. The drum device displays much less hysteretic behavior than the beam, and the detected amplitude signal for the former is more than 3 orders of magnitude larger than for the latter. Nonlinearities (of different strengths or nature) in these systems seem to be the key to understand these facts. We analyze the results in the framework of an extended optomechanical theory including Duffing-type and coupling nonlinear terms. Quantitative understanding of this regime should enable its use as a new resource for microwave electronic circuits. 1. X. Zhou et al., ArXiv:1903.04992 (2019). 2. C. F.
