Abstract

We propose two hybrid configurations that mixed some aspects of a standard double ring resonator (SDR) and a recently proposed cross-coupled double ring resonator (CC-SDR). The SDR is a well-established component of photonic integrated circuits consisting of two microrings that are serially connected by two standard direct-coupled directional couplers (DCs). On the other hand, a CC-SDR is similar to SDR except the interconnections are done with two cross-coupled DCs. Here, the hybrid configurations are implemented with one direct-coupling DC and one cross-coupling DC, instead of the typical two direct-coupling DCs or two cross-coupling DCs. Furthermore, we report that one of the hybrid-double resonator configurations exhibits a new behavior, called shifted coupled resonator induced transparency property.
