Design of a monolithic source of photon pairs comprising a semiconductor laser and a Bragg reflection waveguide
Thomas Tenzler, Jan-Philipp Koester, Hans Wenzel +4
We propose a monolithic, electrically driven source of photon pairs based on a non-linear AlGaAs Bragg reflection waveguide and a laser structure stacked on top. By introducing lat…
Combining Bayesian Optimization, SVD and Machine Learning for Advanced Optical Design
M. R. Mahani, Igor A. Nechepurenko, Thomas Flisgen +1
The design and optimization of optical components, such as Bragg gratings, are critical for applications in telecommunications, sensing, and photonic circuits. To overcome the limi…
Double helical plasmonic antennas
Aleksei Tsarapkin, Luka Zurak, Krzysztof Maćkosz +5
Plasmonic double helical antennas are a means to funnel circularly polarized light down to the nanoscale. Here, an existing design tool for single helices is extended to the case o…
Theory of the linewidth-power product of photonic-crystal surface-emitting lasers
Hans Wenzel, Eduard Kuhn, Ben King +2
A general theory for the intrinsic (Lorentzian) linewidth of photonic--crystal surface--emitting lasers (PCSELs) is presented. The effect of spontaneous emission is modeled by a cl…
Chiral and directional optical emission from a dipole source coupled to a helical plasmonic antenna
Lilli Kuen, Lorenz Löffler, Aleksei Tsarapkin +4
Plasmonic antennas with helical geometry are capable transducers between linearly polarized dipole emission and purely circular polarized far-fields. Besides large Purcell enhancem…
Fabrication of Sawfish photonic crystal cavities in bulk diamond
Tommaso Pregnolato, Marco E. Stucki, Julian M. Bopp +4
Color centers in diamond are quantum systems with optically active spin-states that show long coherence times and are therefore a promising candidate for the development of efficie…
