Si$_3$N$_4$ optomechanical crystals in the resolved-sideband regime

摘要

We demonstrate sideband-resolved Si$_3$N$_4$ optomechanical crystalssupporting $10^5$ quality factor optical modes at 980 nm, coupled to $\approx4$GHz frequency mechanical modes with quality factors of $\approx3000$.Optomechanical electromagnetically induced transparency and absorption areobserved at room temperature and in atmosphere with intracavity photon numbersof the order of $10^4$.
