100 million photons per second from a single organic molecule
Siwei Luo, Tim Hebenstreit, Alexey Shkarin +3
At cryogenic temperatures, organic single-photon sources (SPSs) offer Fourier-limited emission, virtually unlimited photostability, and emission wavelengths selectable by molecular…
Designing metallo-dielectric antennas for cryogenic applications
Siwei Luo, Tim Hebenstreit, Alexey Shkarin +3
We present the design of cryogenic metallo-dielectric antennas tailored to single organic emitters, where the choice of host material imposes specific constraints on the antenna ge…
Nano-electronvolt Fourier-limited transition of a single surface-adsorbed molecule
Masoud Mirzaei, Alexey Shkarin, Burak Gurlek +7
High-resolution spectroscopy allows one to probe weak interactions and to detect subtle phenomena. While such measurements are routinely performed on atoms and molecules in the gas…
High-resolution Cryogenic Spectroscopy of Single Molecules in Nanoprinted Crystals
Mohammad Musavinezhad, Jan Renger, Johannes Zirkelbach +6
We perform laser spectroscopy at liquid helium temperatures (T=2 K) to investigate single dibenzoterrylene (DBT) molecules doped in anthracene crystals of nanoscopic height fabrica…
Quantum Efficiency of Single Dibenzoterrylene Molecules in para-Dichlorobenzene at Cryogenic Temperatures
Mohammad Musavinezhad, Dominik Rattenbacher, Alexey Shkarin +4
We measure the quantum efficiency (QE) of individual dibenzoterrylene (DBT) molecules embedded in para-dichlorobenzene at cryogenic temperatures. To achieve this, we apply two dist…
Spectral splitting of a stimulated Raman transition in a single molecule
Johannes Zirkelbach, Burak Gurlek, Masoud Mirzaei +4
The small cross section of Raman scattering poses a great challenge for its direct study at the single-molecule level. By exploiting the high Franck-Condon factor of a common-mode…

Integrated photonic circuits offer a promising route for studying coherent cooperative effects of a controlled collection of quantum emitters. However, spectral inhomogeneities, de…
High-resolution vibronic spectroscopy of a single molecule embedded in a crystal
Johannes Zirkelbach, Masoud Mirzaei, Irena Deperasinska +6
Vibrational levels of the electronic ground states in dye molecules have not been previously explored at high resolution in solid matrices. We present new spectroscopic measurement…
Single-molecule vacuum Rabi splitting: four-wave mixing and optical switching at the single-photon level
André Pscherer, Manuel Meierhofer, Daqing Wang +5
A single quantum emitter can possess a very strong intrinsic nonlinearity, but its overall promise for nonlinear effects is hampered by the challenge of efficient coupling to incid…
Nanoscopic charge fluctuations in a gallium phosphide waveguide measured by single molecules
Alexey Shkarin, Dominik Rattenbacher, Jan Renger +5
We present efficient coupling of single organic molecules to a gallium phosphide subwavelength waveguide (nanoguide). By examining and correlating the temporal dynamics of various…
Partial cloaking of a gold particle by a single molecule
Johannes Zirkelbach, Benjamin Gmeiner, Jan Renger +4
Extinction of light by material particles stems from losses incurred by absorption or scattering. The extinction cross section is usually treated as an additive quantity, leading t…
