The analytic spectral transmittance of lattice-form and birefringent interleaver filters are revealed to be equivalent mathematically. The corresponding relationship between structural parameters of the two kinds of interleaver filters is also presented. With this mathematical equivalence relationship, we can easily obtain the optimum circuit parameters for designing a lattice-form interleaver filter by using the structural parameters of birefringent interleaver filter obtained by a simple numerical method developed by us recently instead of the complex algorithm based on scattering matrix factorization. More choice of structural parameters with any required spectral transmittance (channel spacing, flatness, isolation and ripple) can be obtained using this method when compared with results presented in references.
