Abstract
The optical transmission between two metalized optical fiber tips with sub-wavelength open apertures was studied for tip-to-tip distances down to ten nanometers. Transverse transmission maps with sub-wavelength structures clearly indicated optical near-field coupling. Depending on light polarization in the emission fiber tips one or two transmission peaks were observed. All these results were explained by a straightforward analytical model.
