Abstract

In this paper, we propose new types of dual microring resonators coupled via 3×3 couplers. By employing the transfer matrix method, a model for these four types is developed and analytical expressions for characterizing their transmissions are derived. The first two types show a coupled-resonator-induced-transparency-like transmission spectrum at the through port. The third type holds the same transmission spectrum, while the last type simultaneously realizes a first-order and a second-order filters at two drop ports. The effects of coupling coefficients on their transmission spectra are analyzed in more detail. These proposed types can be found applications in fields such as sensors and filters.
