Abstract

We introduce a method to estimate the coupling coefficients of the guided field amplitude and the corresponding angular bandwidth in a multimode slab waveguide. This scalar diffraction theory approach is simpler than the more rigorous electromagnetic treatment and is directly applicable to communications systems that use large (dimensions or numerical aperture) waveguides, as in substratemode interconnects. Moreover, this method provides conceptual insight as to a parameter’s effect on the field-amplitude mode distribution and angular bandwidth.
