To get rid of multimode effects narrowband frequency filtering is frequently applied to achieve a single-mode behavior. A rigorous theoretical description to accurately describe the effects of filtering on PDC, however, is still missing. To date, the theoretical models of filtered PDC are rooted in the discrete-variable domain and only account for filtering in the low-gain regime, where only a few photon pairs are emitted at any single point in time. In this paper we extend these theoretical descriptions and put forward a simple model, which is able to accurately describe the effects of filtering on PDC in the continuous-variable domain.

As counterpart to conventional radio antennas, they are able to increase optical felds in sub-wavelength volumes, to enhance excitation and emission of quantum emitters or to direct light, radiated by quantum emitters. The directed emission of these antennas has been mainly pursued by surface plasmon based devices, e.g. Yagi-Uda like antennas, which are rather complicated due to the coupling of several metallic particles. Also, like all metallic structures in optical or infrared regime, these devices are very sensitive to fabrication tolerances and are affected by strong losses. It has been shown recently, that such directed emission can be accomplished by dielectric materials as well. In this paper we present an optimization of nanoscopic antennas in the near infrared regime starting from a metallic Yagi-Uda structure. The optimization is done via a particle-swarm algorithm, using full time domain finite integration simulations to obtain the characteristics of the investigated structure, also taking into account substrates. Furthermore we present a dielectric antenna, which performs even better, due to the lack of losses by an appropriate choice of the dielectric material. These antennas are robust concerning fabrication tolerances and can be realized with different materials for both the antenna and the substrate, without using high index materials.}}, author = {{Hildebrandt, Andre and Reichelt, Matthias and Meier, Torsten and Förstner, Jens}}, booktitle = {{Ultrafast Phenomena and Nanophotonics XVIII}}, editor = {{Betz, Markus and Elezzabi, Abdulhakem Y. and Song, Jin-Joo and Tsen, Kong-Thon}}, keywords = {{tet_topic_opticalantenna}}, pages = {{89841G--8941G--6}}, publisher = {{SPIE}}, title = {{{Engineering plasmonic and dielectric directional nanoantennas}}}, doi = {{10.1117/12.2036588}}, volume = {{8984}}, year = {{2014}}, } @article{15864, abstract = {{Starting from the extended Su-Schrieffer-Heeger model, multiband semiconductor Bloch equations are formulated in momentum space and applied to the analysis of the linear optical response of semiconducting carbon nanotubes (SCNTs).

To validate the test instrument and the underlying PCK model, a think aloud study with 15 probands was conducted. We focused on the knowledge areas that the probands referred to while answering the items. With these data, indications of the validity of the underlying model could be identified.

In den ersten beiden geht es um Wellenausbreitung in zufälligen Potentialen, einmal in einem Mikrowellenaufbau und einmal in einem akustischen Experiment. Der Fokus liegt hier auf den nicht-Gaußschen Eigenschaften der Messgrößen. Das dritte System ist ein typisches Beispiel für vollchaotische offene Systeme mit fraktalem Repeller. Damit untersuchen wir die Verbindung zwischen klassischen periodischen Bahnen und quantenmechanischen Größen. Im ersten Experiment bauen wir in die Mikrowellenkavität ein Potential ein, indem wir metallische Streukörper auf der Bodenplatte zufällig verteilen. In ortsaufgelösten Messungen können wir die gesamte Wellenfunktion untersuchen und finden starke Fluktuationen in der Intensität der Wellenfunktion. Besonders hohe Intensitäten finden sich dort, wo das analoge klassische System Kaustiken ausbildet. Außerdem wird untersucht, in welchem Abstand zur Quelle die Verästelungen starker Intensität anfangen, und ihre Skalierung bezüglich der Eigenschaften des Potentials getestet. Der vorhergesagte Exponent von $-2/3$ kann reproduziert werden. Da bei den hohen Frequenzen, bei denen gemessen wurde, mehrere Moden in der Kavität offen sind, konnten zusätzlich Effekte durch Interferenz von Moden und Koppeln zwischen Moden gefunden werden, die nicht in den theoretischen Modellen berücksichtigt sind. Erst ein störungstheoretischer Ansatz für die Helmholtz-Gleichung zeigt für nicht parallele Deckel- und Bodenplatte, dass es zusätzliche Quellterme für eine Mode durch die jeweils anderen Moden gibt. Dieser Effekt kann in dem experimentellen Daten bestätigt werden. Im zweiten Experiment mit dem akustischen Aufbau wurde der Schall, der von einer turbulenten Luftströmung verursacht wird, gemessen. Die Ergebnisse weichen stark von einer Gaußverteilung der Intensitäten ab, die der zentrale Grenzwertsatz vorhersagt. In einem zweiten Experiment in einem großen Windkanal wird zusätzlich ein Ton defnierter Frequenz durch den Luftstrom gesendet. Die Hoffnung, aus der Modulation dieses Signals Rück-schlüsse auf die Eigenschaften der Turbulenz ziehen zu können, wird nicht erfüllt. Aber wieder wird nicht-Gaußsches Verhalten gefunden. Für den dritten Teil der Arbeit kommen wieder Mikrowellenexperimente zum Einsatz, um ein weiteres komplexes System zu erforschen. Das sogenannte emph{n}-Scheiben System besteht aus emph{n} gleich-artigen Scheiben, die auf einem gleich-seitigen Polygon in einer zweidimensionalen Ebene positioniert sind. In solch offenen Systemen sind die Resonanzen nicht mehr reell, sondern komplex. Diese aus unseren Messdaten zu extrahieren, erfordert einen ausgefeilten Algorithmus, die harmonische Inversion. Die Herausforderungen der Reso-nanzextrahierung werden angesprochen und Lösungsvorschläge diskutiert. Die letztendlich erhaltenen Resonanzen werden benutzt, um die Zählfunktion der Realteile aufzustellen. Ihr Wachstum ist in führender Ordnung durch die Hausdorff-Dimension gegeben. Die Verteilung der Imaginärteile wird in Abhängigkeit der Öffnung des Systems untersucht. Der größte der aus-schließlich negativen Imaginärteile gibt die spektrale Lücke an. Diese wird mit den Vorhersagen verglichen, die auf Berechnungen über die periodischen Bahnen beruhen. Auch für die Abhängigkeit des Maximums der Verteilung von der Öffnung des Systems gibt es theoretische Annahmen, die auf ähnlichen Berechnungen beruht. Diese konnte ebenfalls unterstützt werden.
