Subdiffraction Focusing Enabled by a Fano Resonance

Radiationless electromagnetic interference (REI) has been used to achieve focusing below Abbe’s diffraction limit. Here, we demonstrate an approach to REI that uses the Fano resonance of subwavelength slits to achieve subdiffraction focusing. Two main features of the Fano resonance are critical: (1)...
