Ultrahigh-Q/V single cell slotted nanocavity operated in water

By tuning 30 or more holes, H1 slotted nanocavities with theoretical Q exceeding 10(5) and mode volume smaller than 0.03 (lambda/n)(3) in water were designed. A Q factor exceeding 10(4) was measured in ultrapure water. (C) 2019 The Author(s)
