Field enhancement and funneling of light in combinations of MIM resonators

Plasmonic metal-insulator-metal resonators can be designed to totally absorb an incident light. A combination of such antennas within a sub-wavelength period allows a sorting of the absorbed photons as a function of their wavelength. These structures also exhibit a high electric field enhancement in tiny volumes. We show that this enhancement can be even stronger when the resonator are illuminated with a focused light.
