Light–Matter Coupling Strength Controlled by the Orientation of Organic Crystals in Plasmonic Cavities

In our just accepted manuscript in the Journal of Physical Chemistry C, we demonstrate the coupling of excitons in tetracene crystals to optical modes in open cavities formed by anisotropic arrays of plasmonic nanoparticles and investigate the coupling strength as a function of the alignment to the cavity field. This alignment is realized by rotating a single tetracene crystal on top of an array of silver nanoparticles. The strong light-matter coupling regime is achieved at certain angles. Strong coupling is important because it modifies the photo-physics of organic crystals, as we have demonstrated in our publication in Advanced Functional Materials. You can read more here.
