Abstract
A system and method include a resonator device including walls forming a channel, where the walls are shaped to simultaneously confine light in an optical mode and to confine vibration in a mechanical mode, and where the mechanical mode is selected so that vibration in the mechanical mode can couple to the optical mode. A waveguide is coupled with the resonator device for guiding a probe light through the resonator device. An electro-mechanical actuation mechanism provides a mechanical drive force to the resonator device. A photodetector measure light outputted by the waveguide after passing through the resonator device, the outputted light including a modulated version of the probe light based on passing through the resonator device and interacting with a fluid, or a fluid containing a particle, contained by the channel of the resonator device.
