Si3N4 Optomechanical Crystals in the Resolved-sideband Regime.

摘要

We demonstrate sideband-resolved Si3N4 optomechanical crystals supporting 10(exp5) quality factor optical modes at 980 nm, coupled to nearly equal to 4 GHz frequency mechanical modes with quality factors of nearly equal to 3000. Optomechanical electromagnetically induced transparency and absorption are observed at room temperature and in atmosphere with intracavity photon numbers in excess of 10(exp4).
