An algorithm is proposed for the design of both uniform and nonuniform arrays of coupled waveguides. The algorithm identifies the array parameters which support different number of modes. It uses a general cutoff dispersion function which eliminates the need to solve complex dispersion equations. Numerical examples are included to verify the utility of the proposed algorithm.
