Exploring rotational resonance in elastic metamaterial plates to realize doubly negative property
Wei Wang, Bernard Bonello, Bahram Djafari-Rouhani +2
We report the realization of simultaneously negative effective mass density and shear modulus in a single-phase asymmetric double-sided pillared metamaterial. The negative effectiv…
Low-power phonon lasing through position-modulated Kerr-type nonlinearity
P. Djorwe, Y. Pennec, B. Djafari-Rouhani
We demonstrate low-power amplification process in cavity optomechanics (COM). This operation is based on the nonlinear position-modulated self-Kerr interaction. Owing to this nonli…
Frequency locking and controllable chaos through exceptional point in optomechanics
P. Djorwe, Y. Pennec, B. Djafari-Rouhani
We engineer mechanical gain (loss) in system formed by two optomechanical cavities (OMCs), that are mechanically coupled. The gain (loss) is controlled by driving the resonator wit…
