Abstract

The optical properties of titanium-indiffused lithium niobate (Ti:LiNbO₃) waveguides can be analyzed by various methods like effective index method, WKB method, finite element method, matrix method, BPM method, variational method, etc. Among these, the variational method offers a great advantage in estimating the important characteristics of Ti:LiNbO₃ optical waveguides by direct use of controllable fabrication parameters with less computing time. The present work deals with the assessment of optical properties of Ti:LiNbO₃ waveguide, typically at 1.53 and 1.3 micrometer wavelengths, although the method can be extended for other communication wavelengths within the range 0.6 - 1.6 micrometer. Our simulated results on mode profile have been verified with the experimental data.
