A team of researchers from the University of Cologne, the University of Hasselt (Belgium) and the University of St Andrews (Scotland) is establishing the quantum principle of Starken Kopplung tool mechanics for optical rail traffic technology that tackles the machine, one of its longest running problems. Winkelempfindlichkeit in optical Systemen zu überwinden. The study published in Nature Communications titled “Breaking the angular dispersion limit in thin-film optics through ultra-strong light-matter coupling” was published with an ultra-stable polarizing filter for new research in photo, sensors, optical image and display technology. He was trained in studies at the University of Cologne by Prof. Dr. Malte Gather, professor at the Humboldt Center for Nanophotonics and Biophotonics, in the Department of Chemistry and Biochemistry of the Natural Mathematical Sciences of the World.

The optical filter is intended for many quick start applications. Bislang nimt ihre Leistung aber erheblich ab, wenn das Licht in unterschiedlichen Winkeln auf sie trifft, car sich die vom Filter durchgelassene Lichtfarbe je nach Betrachtungswinkel verändert. This reading tool is fundamental and can display the configuration of optical sensors very efficiently.

The international team is engaged in an in-depth research process which has the principle of guaranteeing quantum mechanics: the most efficient installation of lighting and energy of organized materials makes it possible to create polarities.

The traditional Dünnschicht filter is the best in the world, if abwechselnden transparenten Schichten, häufig Metalloxid-Schichten. Licht wird an cesen einzelnen Schichten bijoux teilweise reflected or transmitted. Die Dicke der einzelnen Schichten bestimmt dabei durch construktive and destructive Überlagerung der Lichtwellen den Farbeindruck, vergleichbar andwa mit den schimmernden Farben von Seifenblasen. With roleplay control, you can easily detect transmissions and reflections on filters. This principle ensures that the filter complies with the fundamental legends for the dispersion of the liquid generated – a use of specific components for small wells (blauverschiebung) when installing the filters. In the new solution provided by the Wissenschaftler*innen absorbierende organische Farbstoffe in optical Filter ein, zu einer starken Kopplung des interferierenden Lichts mit den Farbstoffen führt.

„Eigentlich möchte man jegliche Art von Absorption in Spektralfiltern vermeiden, um deren optical Qualität nicht zu beeinträchtigen. “We want the light absorption to be provided by organic materials, a stable polarity pattern with excellent transmissions to work,” said study leader Dr. Andreas Mischok from the University of Cologne.

The team is in contact with this response filter with high stabilization stability, which itself occurs at an extreme rotation speed of more than 80° at a spectral speed of 15 nm. Komplexe Vielschicht-Designs zeigten außerdem Spitzentransmissionswerte von bis zu zu zu 98 Prozent – ​​​​un Wert, den den aktuell besten herkömmlichen Filtern in nichts nachsteht.
Through the collaboration of the group of Professor Dr. Koen Vandewal and the University of Hasselt, we created a polarizing filter in integrated organic photodiodes, a magnetic stripe photo detector, in the research of fortifications and creating hyperspectral images for material characterization and material characterization. für kompakte optischen Sensoren ebnen.

Die Studie zeigt Möglichkeiten auf, die Technologie auf Polymere, Perowskite, Quantenpunkte etere Materialien zu erweitern and damit the new Filterprinzip auf einen noch grand Wellenlängenbereich zu übertragen. Zu den möglichen Anwendungsgebieten der Polaritonfilter gehören Mikrooptik, Displays, Sensortechnologien and Biophotonik. In all these areas, the new design filter system can be improved drastically and its functionality is improved. Professor Malte Gather, from the University of Cologne, commented: “This is a paradigmatic tool in art and woman, as the optical filter comes into play.” Indem wir the Problem der Winkeldispersion mit an Grundlegend new Ansatz angehen, eröffnen wir völlig new Möglichkeiten für optical Systeme.“

Das Forschungsteam sees the polarizing filter as an einen Eckpfeiler der nächsten Generation optischer Bauteile mit enormen wissenschaftlichem sowie wirtschaftlichem Potential. Neben der Integration der Filter in Sensoren wie LiDAR (Light Detection and Ranging) et der Fluoreszenzmikroskopie stehen Anwendungen in der Displaytechnologie im Zentrum zukünftiger Arbeiten.
