Plasmon spectra of nanospheres under a tightly focused beam
Nassiredin M. Mojarad, Vahid Sandoghdar, Mario Agio
We study the modification of the far-field cross sections and the near-field enhancement for gold and silver nanospheres illuminated by a tightly focused beam. Using a multipole-ex…
Realization of two Fourier-limited solid-state single-photon sources
R. Lettow, V. Ahtee, R. Pfab +4
We demonstrate two solid-state sources of indistinguishable single photons. High resolution laser spectroscopy and optical microscopy were combined at T = 1.4 K to identify individ…
Efficient coupling of photons to a single molecule and the observation of its resonance fluorescence
Gert Wrigge, Ilja Gerhardt, Jaesuk Hwang +2
Single dye molecules at cryogenic temperatures display many spectroscopic phenomena known from free atoms and are thus promising candidates for fundamental quantum optical studies.…
Scanning Near-Field Optical Coherent Spectroscopy of Single Molecules at 1.4 Kelvin
I. Gerhardt, G. Wrigge, M. Agio +3
We present scanning near-field extinction spectra of single molecules embedded in a solid matrix. By varying the molecule-tip separation, we modify the line shape of the spectra, d…
