We experimentally demonstrate that a single nanoparticle can induce mode splitting of MHz in an ultra-high-Q microtoroid resonator, which can be used to extract information of the nanoparticle. Analytical model matches well with the experiments.
We present an experiment where the motion of a silicon micro-mechanical resonator is optically monitored in a high-finesse cavity with a quantum-limited sensitivity. Directs effects of intracavity radiation pressure are experimentally demonstrated. Further experimental progress and cryogenic operation may allow for quantum optics experiments and lead to the experimental observation of the quantum...
We demonstrate, for the first time, independent control over mechanical and optical properties within single chip-scale optomechanical resonators. The direct observation of micromechanical normal-mode splitting enables combining ultra-high optical finesse with material-loss limited mechanical Q-factors.
We report on multiple resonant cavities coupled to a single photonic crystal waveguide operating as a multi-channel sensor. This device is characterized by as many dips in its transmission spectrum as there are cavities. Good reproducibility is observed between the spectrum of double-channel device and those of the single cavities. Infiltration of isopropanol in the holes leads to a red shift of the...
