Si $_3$ N $_4$光机械晶体的分辨边带区

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

Marcelo Davanco, Serkan Ates, Yuxiang Liu, Kartik Srinivasan

摘要:

我们展示了边带分辨的Si $_3$ N $_4$光机械晶体,其支持980 nm处的$10^5$品质因数光学模式,耦合到具有$\approx3000$品质因数的$\approx4$ GHz频率机械模式。在室温和大气中观察到腔内光子数为$10^4$量级的光机械电磁感应透明和吸收。

英文摘要:

We demonstrate sideband-resolved Si$_3$N$_4$ optomechanical crystals supporting $10^5$ 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 are observed at room temperature and in atmosphere with intracavity photon numbers of the order of $10^4$.
