Improved Analysis of the Coupling of Optical Waves into Multimode Waveguides Using Overlap Integrals
The optical multimode interconnection technology has become important due to increasing data rates in modern multi-processor systems. In this context, the coupling of optical waves into multimode waveguides has to be analyzed. Ray optical methods are preferred,but are not applicable for all geometries. As full-wave analysis using the mode matching technique is very extensive,we present a simple method based on overlap integrals, to calculate the coupling efficiency of impinging optical waves. Our approach neglects reflected waves. The corresponding error is corrected by applying a transmission factor,which is that of a plane wave irradiating a dielectric half space. We verify our approach at a planar slab waveguide and a cylindrical fiber, as their mode spectra are well known. The mode matching technique is applied as reference method and the impinging wave is a Gaussian beam with varying angles of incidence and lateral displacements.
