RT info:eu-repo/semantics/article T1 Characterization of Microring Filters for Differential Group Delay Applications A1 Doménech, David A1 Chamorro Posada, Pedro A1 Fraile Peláez, Francisco Javier A1 Erro, María José A1 Tainta, S. A1 Muriel, Miguel A1 Baños, Rocío A1 Bolten, J. A1 Kleinjans, H. AB The longitudinal offset technique permits to improve the accuracy of the coupling coefficients of integrated directional couplers and provides designs that can be easily implemented with current fabrication tolerances. In this paper, we address the additional degree of freedom offered by this technology in order to tailor the differential group delay in coupled-resonator optical filters. We present the characterization of several devices exploiting this feature and we discuss their potential applications.
