A plasmonic nanoantenna based triggered single photon source
Jako Straubel, Robert Filter, Carsten Rockstuhl +1
Highly integrated single photon sources are key components in future quantum-optical circuits. Whereas the probabilistic generation of single photons can routinely be done by now,…
Nonlocal effects: relevance for the spontaneous emission rates of quantum emitters coupled to plasmonic structures
Robert Filter, Christoph Bösel, Giuseppe Toscano +2
The spontaneous emission rate of dipole emitters close to plasmonic dimers are theoretically studied within a nonlocal hydrodynamic model. A nonlocal model has to be used since qua…
Nanoantennas for ultrabright single photon sources
Robert Filter, Karolina Slowik, Jakob Straubel +2
We propose to use nanoantennas coupled to incoherently pumped quantum dots for ultra-bright single photon emission. Besides fully quantum calculations, we analyze an analytical exp…
Strong coupling of optical nanoantennas and atomic systems
Karolina Słowik, Robert Filter, Jakob Straubel +2
An optical nanoantenna and adjacent atomic systems are strongly coupled when an excitation is repeatedly exchanged between these subsystems prior to its eventual dissipation into t…
Tunable Graphene Antennas for Selective Enhancement of THz-Emission
R. Filter, M. Farhat, M. Steglich +3
In this paper, we will introduce THz graphene antennas that strongly enhance the emission rate of quantum systems at specific frequencies. The tunability of these antennas can be u…
Controlling the Dynamics of Quantum Mechanical Systems Sustaining Dipole-Forbidden Transitions via Optical Nanoantennas
Robert Filter, Stefan Mühlig, Toni Eichelkraut +2
We suggest to excite dipole-forbidden transitions in quantum-mechanical systems by using appropriately designed optical nanoantennas. The antennas are tailored such that their near…
Circular Optical Nanoantennas: An Analytical Theory
Robert Filter, Jing Qi, Carsten Rockstuhl +1
An entirely analytical theory is provided for describing the resonance properties of optical nanoantennas made of a stack of homogeneous discs, i.e. circular patch nanoantennas. It…
