Ultrahigh-Q optomechanical crystal cavities fabricated in a CMOS foundry

          Abstract: Photonic crystals use periodic structures to create frequency regions where the optical wave propagation is forbidden, which allows the creation and integration of complex optical functionalities in small footprint devices. Such strategy has also been successfully applied to confine mechanical waves and to explore their interaction with light in the …
