Accurate modelling of signal propagation on optical interconnects is very important to improve and speed up the progress of integrating optical interconnections into the conventional manufacturing process of electrical-optical layouts. In this paper a model is introduced which represents the coupling of optical power from a laser diode into a dielectric waveguide with a rectangular cross section....
Signal propagation within multimode waveguides with rectangular cross sections is modeled by an approximative determination of the propagating modes. Precondition for the approach is a small difference between the refractive indices of the waveguide's core and cladding leading to a small numerical aperture. The approximation yields good results for modes far away from cutoff. As the roughness between...
