Abstract

We derive a wave coupling theory of nonlocal linear electro-optic effect, and the analytical solutions of the resultant equations are provided. With the solutions we study the nonlocal linear electro-optic effect in crystals of different symmetry groups. It shows that the nonlocality of χ̄<sup>(2)</sup> plays a non-negligible role on the linear electro-optic effect only when the nonlocal characteristic length of χ̄<sup>(2)</sup> is comparable with the beam width, and the output beam is no longer Gaussian shape as the input beam in an electro-optic amplitude modulation when nonlocality of χ̄<sup>(2)</sup> is non-negligible. Methods to measure the nonlocal characteristic lengths of of χ̄<sup>(1)</sup> and χ̄<sup>(2)</sup> are also discussed.
