Abstract
The dependence of coupling length and coupling efficiency on waveguide separation of a three waveguide coupler is compared with the results of a conventional directional coupler. In a multimode coupler the coupling length cannot be evaluated directly from the field distributions, a spectral analysis of the fields is necessary. The measurements are made with electromagnetic waves (A = 6mm) in model waveguides and compared with numerical calculations by Beam-Propagation-Method (BPM).
