Abstract:
A technology for the formation of one- and two-dimensional structures by means of interfering (electromagnetic or acoustic) waves and a homogeneous electric field has been proposed. This technology has made it possible to retune the spatial period of the structure during its operation by varying the frequency of interfering waves and the angles of their incidence onto a crystal. It has been shown that the duration of the technological cycle slightly exceeds the domain switching time. The technology is applicable to crystals of LiNbO$_3$, KTiOPO$_4$ (with a high potassium content), and some others.
