In addition, the element is realized by selecting ferroelectric material from a group comprising lithium niobate, lithium tantalate, impurity-doped lithium niobate, and impurity-doped lithium tantalate, each with virtually stoichiometric composition, and processing it into the cylindrical ferroelectric single crystal with a virtually completely round cross-section.
