Schematic of a hypothetical device with a potential difference V across two electrodes separated by a width w; a cladding material (grey) with permittivity C, susceptibility (1)C and width wC; and an EO material (green) with permittivity BTO, susceptibility (1)BTO and width wBTO. The blue line marks how the boundary condition at the bottom of the diagram affects the electric-field strength in each material assuming BTO > C.
