  We propose and demonstrate a hybrid photonic-plasmonic nanolaser that
combines the light harvesting features of a dielectric photonic crystal cavity
with the extraordinary confining properties of an optical nano-antenna. In that
purpose, we developed a novel fabrication method based on multi-step
electron-beam lithography. We show that it enables the robust and reproducible
production of hybrid structures, using fully top down approach to accurately
position the antenna. Coherent coupling of the photonic and plasmonic modes is
highlighted and opens up a broad range of new hybrid nanophotonic devices.
