Abstract

We report the design and experimental realization of a new type of microring filters consisting of two parallel-cascaded microring doublets connected by a π-phase shift element. Interference between the two second-order microring stages gave rise to a fourth-order filter response with flat-top passband and a bandwidth of 100GHz. The result demonstrates the feasibility of realizing advanced integrated optics filters based on parallel cascades of high-order microring networks.
