Ultrasharp Fano Resonances Based on the Circular Cavity Optimized by a Metallic Nanodisk
A compact structure is proposed to achieve double ultrasharp Fano profiles, which comprises with a metal-insulator-metal (MIM) bus waveguide coupled with a circular cavity and groove resonator. Simulation results show that this two sharp Fano profiles both originate from the interference between the...
