Observation of Photon-Phonon Correlations Via Dissipative Filtering

Research output: Contribution to journalArticlepeer-review


Cavity optomechanics enables photon-phonon interaction and correlations by harnessing the radiation-pressure force. Here, we realize a "cavity-in-a-membrane"optomechanical architecture, which allows detection of the motion of lithographically defined, ultrathin membranes via an integrated optical cavity. Using a dissipative filtering method, we are able to eliminate the probe light in situ and observe photon-phonon correlations associated with the low-frequency membrane mechanical mode. The developed method is generally applicable for study of low-frequency light-scattering processes where conventional frequency-selective filtering is unfeasible.
