Three-dimensional nanoconfinement of broadband optical energy in all-dielectric photonic nanostructure
Fig. 1. (a) Plot of the FOM versus the effective confinement area enables a comparison of the nanostructure, optical lens focusing, plasmonic lenses (hollow square [4], solid square [5], hollow circle [6], solid circle [7], hollow triangle [8], solid triangle [8]) and nanofocusing (hollow pentagon [10], solid pentagon [11], hollow diamond [12], solid diamond [13]). The gray area marks the diffraction-limited. The curve of the FOM for the nanostructure is calculated when
