Abstract
We describe the reactive ion etching of Ti:LiNb O3 single crystal in gas mixtures containing C3 F8 and Ar using neutral loop discharge plasma. The surface roughness of etched Ti:LiNb O3 surface under various gas mixture conditions was analyzed by using atomic force microscopy and scanning electron microscopy. The annealing effect of an etched ridge structure waveguides was also observed.
