Abstract

Nanomechanical devices are of immense interest for measuring minuscule quantities with ultimate detection responsivity. Due to their very small mass such devices are extremely sensitive to small fluctuations in the environment and thus allow for making superior sensors. However, because of their small dimensions efficient transduction mechanisms are challenging to develop, both to readout their mechanical motion and to drive them into oscillation. An intriguing property of nanoscale resonators is the fact that they are size-matched to nanophotonic components. Therefore they can be seamlessly integrated into on-chip photonic circuits which enables using optical methods for readout and actuation. In this case the link between mechanical and optical domains is the gradient optical force which can be harnessed for integrated optomechanical interactions. Because gradient forces are a generic optical concepts they can be generated in a wide range of material systems and thus also provide a way to give active functionality to optical circuits where alternative tuning mechanisms do not exist.
