Popis: | A ring resonator modulator based on double-layer graphene and Chalcogenide glasses waveguide is presented and investigated. Wide bandwidth mid-infrared light operation can be achieved. A strong interaction between mid-infrared light and graphene is obtained, which change the effective mode index in the waveguide significantly while the change of applied voltage. Besides, the modulator we proposed owns a large extinction ratio of 33.57 dB. |
