Show affiliationsAnalysis of a design scheme that relaxes alignment issues is reported. This entails the use of vertically coupled microring resonators (MR). It is shown that an almost flat response of the coupling coefficient to offset values up to 1 µm is feasible by judicious choice of the bus and ring waveguide geometry. The scheme is evaluated using FDTD simulations and its applicability to functional devices is probed via the transfer-matrix method of the transmission characteristics of microring-based filters.
