Flexoelectro-optic liquid crystal analog phase-only modulator with a 2π range and 1  kHz switching

Abstract:

We present a flexoelectro-optic liquid crystal (LC) analog phase modulator with >2𝜋 phase range at a 1 kHz switching frequency. The chiral nematic LC mixture consists of the bimesogen CBC7CB with chiral dopant R5011, aligned in the uniform lying helix mode. The mixture exhibits >±𝜋/4 rotation of the optic axis for a drive voltage of ±21.5  V (𝐸=±4.5  V μm−1). The rotation of the optic axis is converted into a phase modulation with the aid of a reflective device configuration incorporati...
