Coherent Nonlinear Single Molecule Microscopy
Ilja Gerhardt, Gert Wrigge, Jaseuk Hwang +2
We investigate a nonlinear localization microscopy method based on Rabi oscillations of single emitters. We demonstrate the fundamental working principle of this new technique usin…
Control and imaging of single-molecule spectral dynamics using a nano-electrode
Ilja Gerhardt, Gert Wrigge, Vahid Sandoghdar
We study the influence of a scanning nano-electrode on fluorescence excitation spectra of single terrylene molecules embedded in thin p-terphenyl films at cryogenic temperatures. W…
Coherent State Preparation and Observation of Rabi Oscillations in a Single Molecule
Ilja Gerhardt, Gert Wrigge, Gert Zumofen +3
We report on the excitation of single molecules via narrow zero-phonon transitions using short laser pulses. By monitoring the Stokes-shifted fluorescence, we studied the excited s…
Exploring the limits of single emitter detection in fluorescence and extinction
Gert Wrigge, Jaesuk Hwang, Ilja Gerhardt +2
We present an experimental comparison and a theoretical analysis of the signal-to-noise ratios in fluorescence and extinction spectroscopy of a single emitter. We show that extinct…
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…
