The interplay between quantum dots and plasmonic nanoantennas may have a critical role in the behavior of photonics devices. A mixed top-down and bottom-up nanofabrication approach has been used to realize a prototype of photonic-plasmonic transistor, including a nano-guided hybrid system able to promote the interaction between gold nanostructures and quantum dots in a plasmon-exciton exchange procedure. In particular, photopolymerization by evanescent to fabricate a polymer ridge containing quantum dots directly on top of the hybrid system. A first characterization, has evidenced a sensitive enhancement of the emission of the quantum dots located close to the apices of nanostructures.
