Coupling organic molecules to nanophotonic cavities to study collective effects

Organic dye molecules have recently shown promise as sources of single photons. When cooled to liquid helium temperatures, dibenzoterrylene molecules in anthracene crystals exhibit lifetime-limited linewidths with a high probability of decay onto the zero-phonon line and minimal spectral wandering. Due to a charge transport phenomenon, laser light can be used to induce long-term frequency shifting on the order of the system's inhomogeneous broadening. This may allow for the efficient fine-tuning of frequencies to realize many-body resonant interactions in the solid state. We will present a strategy to couple multiple nearly resonant dibenzoterrylene molecules to a nanophotonic cavity to study collective effects.
