Performance analysis of three dimensional high index contrast dielectric waveguides

This paper presents the implementation of a parallelized Finite- Difference Time-Domain method, based on the Message Passing Interface (i.e. MPI), which is used to study the modal properties of three-dimensional (3D) dielectric waveguide structures. To this end, we also use the leastsquare method to obtain the wave vector, beta, along the axis of propagation. Lastly, bending losses in arbitrary-angle waveguides are also discussed.
