We report our recent results of investigation of the interactions between localized plasmons in gold nanorods and excitons in J-aggregates. We were able to track an anticrossing behavior of the hybridized modes both in the extinction and in the photoluminescence spectra of this hybrid system. We identified the nonlinear optical behavior of this system by transient absorption spectroscopy. Finally...
Recent advances on Surface Enhanced Raman Scattering (SERS) have led to a delicate control of the coupling between extremely-confined plasmonic resonances supported by metallic structures and the vibrational states of molecules. As a consequence, experiments have started to emerge that cannot be easily explained using standard models based on the classical enhancement of the plasmonic fields near...
Optical nano antennas are currently promising key elements for sensing and optical communication [1, 2]. They may resonate even when they are much smaller than the wavelength. However, this extraordinary behaviour makes the design and simulation very difficult. Traditional RF antennas are essentially scalable, which implies relatively simple design rules [3]. In contrast to this, plasmonic nano antennas...
The interaction between the excitonic J-band of J-aggregate molecules and localized plasmonic resonances supported by metallic structures can be large enough to reach the regime of strong coupling, giving rise to two hybridized modes [1, 2]. The new hybrid system is often characterized in extinction measurements, where the strong coupling results in an avoided crossing of the two modes as the detuning...
We present our recent results on the development and characterization of hybrid sytems consisting of plasmonic nanostructures and organic dye molecules in a J-aggregate state. The measured spectra exhibit a strongly suppressed signal at wavelengths which correspond to the J-aggregate band, which is indicative of strong interaction between the plasmonic and excitonic systems.
