Optical microscopy via spectral modifications of a nano-antenna
T. Kalkbrenner, U. Hakanson, A. Schädle +3
The existing optical microscopes form an image by collecting photons emitted from an object. Here we report on the experimental realization of microscopy without the need for direc…

Measuring the quantum efficiency of single radiating dipoles using a scanning mirror
B. C. Buchler, T. Kalkbrenner, C. Hettich +1
Using scanning probe techniques, we show the controlled manipulation of the radiation from single dipoles. In one experiment we study the modification of the fluorescence lifetime…
