Novel technique for analysis and design of diffused Ti:LiNbO3 optical planar waveguides

Abstract

In this work is presented a new efficient and simple method, which allows the analysis and design of planar optical waveguides. This method links the desired performances of the optical waveguides with basic technological parameters. The first four charts of the method can easily be adapted for planar waveguides of arbitrary index profile. The last two charts were obtained experimentally and are valid for diffused Ti:LiNbO3 optical planar waveguides. The main optical parameters may be easily interrelated utilizing a personal computer or drawing simple vertical and horizontal lines on an abacus.
