A bright single photon source: Strong coupling of a single molecule to a plasmonic nano-antenna cavity

Single photon emitters are quantum light sources that can enable a variety of quantum based technologies such as quantum information or quantum random number generation, among others. These single photon emitters can have their brightness increased by coupling to a plasmonic cavity. In this work, th...

In this work, this possibility is addressed by spin coating anthracene crystals hosting dibenzoterrylene (DBT) molecules on top of Au dipolar nanoantenna arrays. Thin anthracene crystals covering a big fraction of the nanoantenna arrays were achieved, on which confocal fluorescence microscopy and time correlated single photon counting have been used to characterize the emitters.
