Nanostructuring lithium niobate substrates by focused ion beam milling
We report on two novel ways for patterning lithium niobate (LN) at submicronic scale by means of focused ion beam (FIB) bombardment. The first method consists of direct FIB milling on LiNbO 3 and the second one is a combination of FIB milling on a deposited metallic layer and subsequent RIE (Reactive Ion Etching) etching. …
