Exceptional point enhances sensitivity of optomechanical mass sensors
P. Djorwé, Y. Pennec, B. Djafari-Rouhani
We propose an efficient optomechanical mass sensor operating at exceptional points (EPs), non-hermitian degeneracies where eigenvalues of a system and their corresponding eigenvect…

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…
