1 Apr 1987 We report the first fabrication, by a double proton exchange process (Double Exchange, DE) of planar LiNbO3 waveguides simultaneously
Simulation of Ti-indiffused waveguides on LiNbO3 is described. The influence of waveguide size, its optical losses per unit length, and its eigen mode structure. These properties the calculations have given a correct result. Nowadays
1 Oct 2010 We demonstrate low-loss chalcogenide (As2S3) waveguides on a LiNbO3 substrate for the mid-IR wavelength Lithium niobate (LiNbO3) is adopted as the substrate . Theoretical calculation shows the Fresnel reflection.
