Linbo3 dry etch
Nettet1. aug. 2011 · Several etching techniques have been demonstrated so far for the fabrication of ridges waveguides in LiNbO3, such as plasma dry etching [1] or wet etching [2]. In particular, ion-beam enhanced etching has demonstrated to be an excellent choice to fabricate structures with high aspect ratios in lithium niobate [3]. NettetThree different novel dry-etching methods have been employed to fabricate nanophotonic devices upon a thin-film lithium niobate on insulator material platform. Different dry …
