Abstract :
A simulation of tapered lithium niobate optical waveguide fabricated by the proton-exchanged method is presented. The Fresnel equation with an initial input field distribution is solved numerically using the semivectorial-polarized finite difference method and the Runge-Kutta method. The calculated and experimental results are in good agreement.<>
