Abstract

Very-deep nanometer-size domain inversions in lithium niobate (LiNbO3) substrate have been realized using circular form full cover electrode (CF-FCE) for the first time. From the calculated results, circular form electrode is better than that of rectangular type for fine domain inversion patterns. Domain inversion was performed by applying high voltage to circular form FCE. Using the CF-FCE, we successfully fabricated 2 mu m periodic domain inversion in a 500-mu m-thick congruent LiNbO3 (CLN) crystal. It is also shown that smaller domain inversion width in the nanometer regime with high aspect ratio is possible using this technique. We obtained an aspect ratio as high as 870 for a domain inversion width of 575 nm.
