Tunable strong coupling — •Daniel Friedrich, Benedikt Schurr, Heiko Gross, and Bert Hecht — NanoOptics & Biophotonics Group, Experimental Physics 5, University of Würzburg, Germany

Using a scanning plasmonic nano resonator we have shown recently how to achieve tunable strong coupling to colloidal CdSe quantum dots at ambient conditions. The developed system provides an elegant method to tune the coupling strength and can also be used as high resolution optical microscope. [1]

In the presentation we highlight the possibility to establish strong coupling with different kinds of emitters that can be placed on any (transparent) substrate. The emitters include a variety of colloidal semiconductor nanoparticles and platelets as well as TMDCs.
