Solmaz, M. E.2016-02-082016-02-0820140950-0340http://hdl.handle.net/11693/26303The fabrication and characterization are reported of a Fano resonance-based electro-optically tunable ring resonator-coupled Mach-Zehnder interferometer device based on a chalcogenide-lithium niobate hybrid waveguide system. The experiments reveal inherent asymmetric lineshapes that can be flipped to a near symmetrical resonance by applying a dc voltage of ~10 V across the electrode at the MZI non-resonator arm. Further increase in voltage yields the reverse of initial asymmetry. The optical filter-based transfer-matrix model easily explains the experimental data and indicates ways to further enhance the usability of such architecture. © 2014 Taylor and Francis.EnglishChalcogenideLithium niobateMach-Zehnder interferometerTunable optical filterChalcogenidesOptical filtersResonanceWaveguidesDC voltageFabrication and characterizationsFilter-basedHybrid waveguidesLithium niobateRing-coupledTransfer-matrix modelingTunable optical filtersMach-Zehnder interferometersArticle10.1080/09500340.2014.890254
