A method for the fabrication of bow-tie optical antennas at the apex of pyramidal Si 3 N 4 atomic force microscopy tips is described. We demonstrate that these novel optical probes are capable of sub-wavelength imaging of single quantum dots at room temperature. The enhanced and confined optical near-field at the antenna feed gap leads to locally enhanced(More)
