Abstract
Microfluidic optomechanical device are a unique optofluidics platform that can exhibit optomechanical oscillation in the 10-20 MHz, driven by radiation pressure (RP). The resonant enhancement of both mechanical and optical response in microcavity optomechanical devices allows exquisitely sensitive measurements of environment stimuli (pressure, force, sound speed change) and non-solid states of matter (freely flowing particles, viscous fluids). In this work, we experimentally investigate temperature tuning of these hollow-shell oscillators. We also demonstrate the effect of temperature on the frequency domain of optical machine oscillation resonance shift and applied it to the field of temperature sensing. Our result is a step towards optomechanical sensor in the field of temperature.
