摘要
A surface-plasmon-polaritons (SPPs) tunable optical resonant ring filter comprises a SPPs waveguide (1), a SPPs tunable directional coupler (2), and a SPPs tunable resonant ring (3).The tunabilities of the resonant frequency, the resonant depth, and the filtering bandwidth are achieved by tuning the loss and transmission phase of the resonant ring (3) and the coupling ratio of the directional coupler (2). Since the metal core layer of the SPPs waveguide is capable of multiplexing electro-optical signals, the SPPs tunable optical resonant ring filter can be used not only in an integrated optics system, but also in an integrated electro-optics hybrid system.
