In this paper we present the investigation of optical filters based on triple ring resonator architectures in silicon-on-insulator technology. The generalized approach based on Mason’s rule and delay line signal processing has been implemented for modeling optical filters in Z-domain. A numerical investigation based on the coefficient map has been adopted for designing optical add-drop multiplexers with wide free spectral ranges, as large as 12 THz (~ 96 nm). Low crosstalk, of the order of -20 dB, has been numerically demonstrated in overall transmittances of optimized filters. Keywords — Free spectral range, optical add-drop multiplexers, ring resonators, silicon-on-insulator

In this paper we present the investigation of optical filters based on triple ring resonator architectures in silicon-on-insulator technology. The generalized approach based on Mason’s rule and delay line signal processing has been implemented for modeling optical filters in Z-domain. A numerical investigation based on the coefficient map has been adopted for designing optical add-drop multiplexers with wide free spectral ranges, as large as 12 THz (~ 96 nm). Low crosstalk, of the order of -20 dB, has been numerically demonstrated in overall transmittances of optimized filters.
