Abstract
A technique for accurate measurement of the linear electro-optic coefficient(s) in crystals that are simultaneously optically active and birefringent is described. It is shown that this technique provides a direct method of measuring field-induced birefringence and so can form the basis of a Bi12SiO20 (or Bi12GeO20) sensor arrangement. The high degree of accuracy obtained in the measurements of the linear electro-optic coefficient in Bi12SiO20 and Bi12GeO20 crystals indicates the particular suitability of these materials in electric-field and voltage-sensor systems with a high dynamic range and for possible waveguiding applications.
