High-speed sensor head with wide frequency range using deformed helix ferroelectric liquid crystal


In this paper we propose a new approach to fiber-optic sensor head based on voltage-controlled ferroelectric liquid crystals (FLC). Using nano-grid electrodes, nanometer-scale photo-alignment layers and deformed helix ferroelectric liquid crystals with a sub-wavelength helix pitch of 150 nm, we have realized a fully integrated polarization-based photonic… (More)
