Recent achievements in domain engineering in lithium niobate and lithium tantalate

We present a survey of our recent study of the field-induced domain kinetics in single-crystalline congruent lithium niobate (LN) and lithium tantalate (LT). The proposed backswitched poling by field application to the lithographically defined metal strip electrodes allows to produce periodical micro-scale structures for nonlinear optical application and to demonstrate the first achievements in domain nano-technology.
