Abstract
A plasma dry etching technique was applied to the fabrication of ridge-shaped LiNbO3 optical waveguides for broadband operation. The etching characteristics of the fabricated LiNbO3 optical waveguides were investigated as functions of the Ar/C3F8 flow ratio and the antenna power by using a neutral loop discharge plasma etcher. Especially, the optimal etching conditions of the ridge shaped LiNbO3 optical waveguide were found to be a C3F8 gas flow ratio of 0.2 and an antenna power of 600 W.
