ABSTRACT
We present an approach to inspecting the electro-optical properties of a ferroelectric crystal on the nanometer scale by applying a confined electric field E between a pointed optical fiber and the sample under investigation. Monitoring the optical transmission of barium titanate (BaTiO[sub 3]) provides a complete image of the ferroelectric domain distribution in a single scan, including also antiparallel domains. The spatial resolution of ∼250 nm in this experiment is determined by the confinement of the electric field. © 2004 American Institute of Physics.
