Electro-optical modulation with silicon microspheres in liquid crystal

We demonstrate electro-optical tuning and modulation of the optical resonances of a silicon microsphere placed on an optical fiber half coupler and immersed in a nematic liquid crystal. The relative refractive index between the microsphere and the liquid crystal is controlled by an applied external AC electric field. The tuning and modulation of the microsphere optical resonances is monitored with the transmission and elastic scattering signals.
