Abstract

In this study, we present electric field (E-field) modelling and experiment of arrays of vertically grown carbon nanotubes as three dimensional electrode structures, in order to address liquid crystal molecules in a switchable nano-photonic device. The electric field spawned by the nanotube electrodes is used to align the liquid crystal molecules to generate a gradient refractive index profile across the device. It was observed that multiple nanotube groups generated wide and symmetrical electric fields compared to other geometries. We have utilized nano-photonic devices based on the simulation results and compared them with experimentally obtained electro-optic characteristics. These devices have many applications in voltage reconfigurable micro-optical systems.
