Beyond linear coupling in microwave optomechanics
D. Cattiaux, X. Zhou, S. Kumar +8
We explore the nonlinear dynamics of a cavity optomechanical system. Our realization consisting of a drumhead nano-electro-mechanical resonator (NEMS) coupled to a microwave cavity…

Geometrical Nonlinearity of Circular Plates and Membranes: an Alternative Method
D. Cattiaux, S. Kumar, X. Zhou +2
We apply the well-established theoretical method developed for geometrical nonlinearities of micro/nano-mechanical clamped beams to circular drums. The calculation is performed und…
