Numerical Calculation of Refractive-Index Profile of Optical Waveguides
The numerical calculating method of refractive index profile in optical waveguides is discussed. By using this method, the two dimensional distribution or line distribution along x, y direction of refractive-index difference can be obtained based on the output pattern of optical waveguides. The measured result of the index difference profile of a Ti:LiNbO3 waveguide in the direction perpendicular to the substrate surface is given.
