In this paper we demonstrate a lattice filter based WDM framework on SOI platform. Finite Impulse Response filter synthesis routines are used to calculate the design specifications. The inputs are functional parameters: normalized cut-off frequency, free spectral range, filter order and windowing function. The obtained specifications are passed to the Caphe circuit simulator. Then we convert the design parameters to physical parameters in IPKISS for layout and mask design. The measured results prove the validity, but also the limitations of the framework. The latter, more pronounced in high order filters, are mainly attributed to errors in the weak coupling sections.
