Abstract

ABSTRACT In this paper, high-order microring resonator filters coupled serially up to the 7th order are proposed for on-chip optical interconnects. This work mainly focuses on achieving a flat-top, higher out-of-band rejection ratio, and enhanced group delay value than previously demonstrated microring filters. Further, the effect of varying inter-resonator coupling coefficients on the filtering operation of wavelength 1552 nm is investigated, using the continued fraction method, and optimum conditions for coupling coefficients between ring-ring waveguides are realized to obtain steep edge response. The proposed design exhibits a minimum group delay of 7.457 ps at a coupling value of 0.04.
