Nanolocalization of time-reversed optical fields (Pfeiffer)

The far field emission pattern of a nanoscale light emitter positioned in a nanoscale random scattering environment contains information about the localized emission. Because of the reciprocity of electromagnetic wave propagation time-reversing the outgoing wave creates an excitation that propagates back to the emitter and localizes on a sub-diffraction limited length scale.


Here we propose to demonstrate this nanolocalization of radiation based on time-reversed fields in the visible range of the electromagnetic spectrum.
