Cavity optomechanics is a rapidly-growing field in which mechanical degrees of freedom are coupled to modes of the electromagnetic field inside optical or microwave resonators. Adapting laser-cooling techniques from atomic physics several experiments have recently observed mechanical motion close to the quantum ground-state. This paves the way to exploit these systems for the engineering of phonon and photons at the nanoscale with exciting, new applications for science and technology [Rev. Mod. Phys. 86, 1391 (2014)].

Along this line of thought, I will give an overview of recent research highlights and an outline of future directions. I am going to discuss synchronisation in the simple quantum-mechanical scenario of one harmonic self-oscillator [PRL 112, 094102 (2014)] as well as a nonlinear self-oscillator [PRL 117, 073601 (2016)] coupled to an external drive. I will then report on the realisation of the reversed dissipation regime of cavity optomechanics [arXiv:1602.05180] in which dissipation of the mechanical oscillator dominates over that of the electromagnetic modes [PRL 113, 023604 (2014)].
