Modeling and performance analysis of vertically coupled triple microring resonator in the Z domain.

A theoretical model of vertically coupled triple microring resonators (VCTMRRs) in the Z domain is presented in this work. Delay line signal processing approach in Z-domain modeling is used for the performance analysis of waveguide-based VCTMRRs. Overall transmittance of the VCTMRR is determined in the Z domain, and frequency response is evaluated in a MATLAB environment.
