  We report an approach to achieve this goal via build a plasmonic-dielectric
photonic hybrid system. We induce a defect mode based photonic crystal (PC)
cavity to work as a intermedium storage as well as a near-field light source to
excite a plasmonic nanoantenna (NA). In this way, a plasmonic-photonic
nano-laser source is created in present experiment. The coupling condition
between the two elements is investigated in far-field and near-field level. We
found that the NA reduces the Q-factor of the PC-cavity. Meanwhile, the NA
concentrates and enhances the laser emission of the PC-cavity. This novel
hybrid dielectric-plasmonic structure may open a new avenue in the generation
of nano-light sources, which can be applied in areas such as optical
information storage, non-linear optics, optical trapping and detection,
integrated optics, etc.
