Abstract :
A three-dimensional method for obtaining the bending losses and field distributions of curved integrated optic rib-waveguides is presented. The method is based on a so called ´line method´ and relies on a discretisation of the potential in the direction of the rib-heights and leads to Bessel-equations in the radial direction. Good agreement with experimental results is obtained.
