摘要: We present both theoretical and experimental evidence that two metal-insulator-metal plasmonic resonators can be combined into a wideband total photon absorber in the mid-infrared. show that, although closely arranged subwavelength period, these behave as angularly independent antennas at their own resonant wavelength. The structures thus allow for an efficient dual color routing collection.
