In this paper, by means of generalized Tschebyshev polynomial, the analytical so lution is derived for (N+1)×（N+1） waveguide couplers arranged in a ring with strong coupling. As a concrete example, the solution of 5×5 waveguide couplers is calculated, and the relationship between strong and weak couplings is analyze d. The property of generalized Tschebyshev polynomial is discussed in detail.
