We design an integrated optics whispering gallery microsphere resonator integrating liquid crystals as tuning medium. Our device consists of a sapphire microsphere positioned over a diffused waveguide in glass substrate. At the base of the microsphere a small volume of liquid crystal is infiltrated. We numerically evaluate the performances of the device and demonstrate a voltage tuning of the narrow band resonances.

Abstract
We design an integrated optics whispering gallery microsphere resonator integrating liquid crystals as tuning medium. Our device consists of a sapphire microsphere positioned over a diffused waveguide in glass substrate. At the base of the microsphere a small volume of liquid crystal is infiltrated. We numerically evaluate the performances of the device and demonstrate a voltage tuning of the narrow band resonances.File in questo prodotto:
